The resolver is a sensor that is utilized to check the magnetic poles positioning, including the motor generator rotor. Obtaining knowledge about the poles position is absolutely necessary to make sure of the exact control of MG2 and MG1. Every resolver is comprised of a stator with an excitation coil and 2 detection coils, S and C. Due to the rotor being oval shaped, this sets up a gap between the stator and rotor, which fluctuates while the rotor is turning. A current that occurs repeatedly with a well-advanced frequency is flowing in past the excitation coil, and detection coils S and C output current also happens repeatedly in a manner conforming to the sensor rotor placement.

The inverter with converter assembly (MG ECU) checks for the complete placement of the rotor in a manner conforming to the stages of detection coils S and C, which includes the measured heights of their waveform Moreover, the CPU estimates the quantity of the changing position inside an advanced outcome in time length, as a way to utilize the resolver in the form of a speed sensor. The MG ECU inspects output signals that are coming from the motor resolver and checks for function failures.

What causes this problem with the Generator Position Sensor Circuit 'A'?

• Defective inverter with converter assembly
• Failed hybrid vehicle generator assembly
• Faulty hybrid vehicle motor assembly
• Damaged wire harness or connector

1. Speed Sensor - The motor resolver is a form of speed sensor that creates a set of waves that signal complete position into a single revolution; these signals are usually changed with a resolver interface board to a digital signal. We visualize that the activity is associated to the speed or position control. The most common disruptions to be seen are when the motor is vibrating, speed rotations are different, strange engine noises, movement positioning accuracy is different, positioning system vibrates, positioning is incorrect, and there are random stops in movement. A majority of modern motor drives and motion/positioning controls perform a run-time monitoring of the process within the calculating equipment and they can detect the most frequent errors and put the motor to a stop. If your local mechanic can look at what is the function of resolver and encoder in the motor, it makes it easier to understand the consequences of errors.
2. Connector - Visible wear or damage is a major symptom of a problem with the motor’s resolver connector. Old cables might dry up and could lead to cracks within the insulation. Cables might run up against a hot manifold or motor component, which might cause them to melt and burn up. These kinds of issues might compromise for a cable’s ability to a surge power through the connector. This can result in misfires and other performance issues, and in more serious cases may even lead to the cables shorting against the engine. Since a majority of modern cars are being made with these motor resolver connectors, which are found on a huge mass of on road cars and trucks, they play a critical role in motor performance. If you surmise that your car might be facing a problem with the motor’s resolver connector, have the car detected by a professional mechanic, such as one at Parts Avatar, to find out if the connector should be replaced.
3. Converter Assembly - The exact issue with a converter defect is possible the start circuit. There has to be a set of capacitors that are in short-term placed in the circuit to step shift the third wire and get the motor turning. This set of orange wires go nowhere, even if they look disconnected, there should be a black wire, in which one connection should be there. The converter usually consists of a contractor, capacitor and a black case that is the potential relay, which is mounted to the motor. Wires can be the result of something hazardous; therefore, you should depend on an experienced mechanic to properly work with this mass of wire and safely recommend where the diagnosis is located.
4. Motor Generator - There is a defect in the generator. A circuit breaker is open. There is bad connection or a defective cord set. A device connection has gone bad. If your generator’s motor is performing well with no load, but when loads are connected, then these causes may possibly happen: There is a short circuit in a connected load. The engine speed is not fast enough. The generator has too much load. There is a short in the generator circuit. There is a plugged/dirty filter. If your generator’s engine will not start, or does start, but runs roughly, then these causes may possibly happen: A battery has failed. Oil is at a low level. An air filter is dirty. There is a loss of fuel. There is a plugged/dirty filter. The fuel has water in it. There is a flooded engine. A spark plug has gone bad. The spark plug wire is disengaged to the plug. The fuel mixture is excessively rich. The intake valve is stuck, open or closed. The engine has lost buildup of pressure. The start switch is set in OFF position. The fuel valve is set in OFF position. If your generator’s motor is running and shuts down, then these causes may possibly happen: There is a plugged/dirty air or fuel filter. The carburetor is running overly rich or overly lean. If your generator engine fails, then these causes may possibly happen: The fuel filter is plugged/dirty. The carburetor is running overly lean or overly rich.

5. Rotor - Any change occurring in working states can interrupt the performance, dependability, and effectiveness in modern high-grade motors and result in rotor failure. Rotors usually fail by two causes: There are too many start-ups. In a few large squirrel-cage rotors, the measure of rotor life span is the opposite order in corresponding to size to the amount of starts. Starting intervals are lengthier than the motor is built for. This circumstance is unexpectedly faced when starting with huge stagnant loads. Damaged rotor bars result in a majority, though not all parts, failed rotors, thus is usually detected inside the slot section of the rotor. In location of the end ring, or shorting ring, this connects the bar. Where the bar accesses the core, its breaks are a result of combined mechanical and electrical pressures. You can find manageable steps to find out if damaged rotor bars actually inhabit the motor assembly. When critical vibrating or other motor issues happen, it is most susceptible that you should visit a repair shop to conduct a complete detection of the motor parts to find out the issue, even if the motor is larger.
6. Detection Coils - A faulty detection coil will basically show some recurrent signs such as the following: an indescribably louder than normal motor. There is a visible loss of power in the motor. The motor speed has a significant plunge in accelerating for no plausible reason. There is a blinking or irregular activation in the check engine light. There is an active gas warning light when the car retains a sufficient amount of fuel. The motor is suddenly releasing an irregular gust of smoke, and runs roughly, rather than performing in a smooth flow. Regards, there is an easier method in checking the detection coils in your car and ensuring they are performing by expectation. You must use an ohmmeter to check the detection coils for constant stream. Ensure that you have the exact ohm values for the detection coils. To gather this data, look up your car’s motor online and buy a helpful manual to help you find out the ohms reading for the detection coils, or have an experienced mechanic do this for you.
7. Motor Resolver - A motor resolver is a vibrating position controller or motor drive that gives a continuous fluctuation in motor positioning or/and motor continuous acceleration-deceleration that is normally easier to detect when the motor is running low in RPM, and some RPM can generate powerful mechanical back and forth movement at a regular speed. Use the Oscilloscope to detect for a position controller output and motor drive input signal, including a motor voltage and current. This method will test for different rotation speeds. You might hear strange engine sounds coming from the motor drive frequency or notice vibrations in the motor position system. So check up mechanical backlashes within the system, as movement-positioning accuracy does vary. As the motor tends to vibrate, so will the positioning system, which means there is something wrong in the positioning system parameters. Therefore, check the position control output to check for incorrect positioning, and then look into the movement positioning for further inaccuracies. There may be random stops in movement, check cable failures and bad contacts, reprise the method of checking the position controller output and motor drive signal, including motor voltage and current. Electrical measurements should be achieved with the oscilloscope, as signals might come with fast changes and different frequencies.

It is very important to acknowledge the symptoms of a problem, as this is when you’ll know how to correct the problem. This is why our team has recommended a few critical symptoms of OBD Code P0C64 as described below:

Common Symptoms

• The engine oil will show dilution by when ECU tries to hike engine temperature. Sometimes, vehicles will slightly advance the fuel injection timing to top center after burning a small quantity of fuel to raise exhaust temperatures. A certain amount of this fuel will access the crankcase. When the ECU finds out the need to regenerate the DPF, the service life of the oil will be considerably short.
• Defective or corroded wiring
• Delay in acceleration
• Declined fuel efficiency

These are a few methods that will help you be able to solve the OBD Code P0C64:

• Adjust or replace circuitry, connectors, and/or vehicle components as needed.
• According to system, this signal is sent forward to impacted control modules that use the data to achieve a variety of other roles.
• CAN is a short-term for Controller Area Network. The CAN stands for a communication bus that enables many microcontrollers to communicate with one another without needing a host computer.
• As exhaust temperature declines with the engine off, circuit resistance raises up and the feedback voltage signal to the PCM drops down.

These are a few methods that you must go through as a way to correctly diagnose this error code:

When you see white smoke, this indicates that the fuel is being inserted into the combustion chamber, but is not getting burned correctly. The recurrent causes that create white smoke differ from a bad engine compression or fuel tampered with water, to a thrown off fuel pump timer, as a component is draining the fuel from accessing the pump in accordance to the needs of the pump to be timing and working properly. The prime thing with the code P0C64 is to detecting for verification in the performance of the VCT solenoid. You are seeking a stuck or sticking VCT solenoid valve that is the result of pollution. We recommend you read a vehicle identified repair manual to conduct auto part inspections for the VCT segment.

Common Mistakes When Diagnosing the P0C64 Code
