P0C61 - OBD Trouble Code

<<See All OBD Codes

OBD-II Code Drive Motor "B" Position Sensor Circuit "B" Low is the means of a Drive Motor "B" Position Sensor Circuit "B" Low.

The Drive Motor Position Sensor communicates with the Motor Control Module about the Drive Motor Output Shaft positioning. If the Motor Control Module is unable to consistently oversee the output shaft positioning, this sets the code P0C61. The Drive Motor Position Sensor is inside of the Drive Motor Generator and is unable to be of distinct service.

The motor control module observes the drive motor generator position sensor. The motor control module then tracks the angular position, speed and direction of the drive motor generator rotor rooted by the signals of the resolver-type position sensor. The position sensor consists of a drive coil, two driven coils and an abnormally formed rotor of metal. Mechanically, the rotor of metal is engaged to the shaft of the drive motor generator. With the car set at ON, the motor control module gives output toward a 7 volt alternating current, and sends an 10 kHz excitation signal toward the drive coil. The drive coil excitation signal produces a magnetic field that encompasses the two driven coils and the abnormally formed rotor. Then the motor control module surveys the two driven coil circuits for a signal to come back. The placement of the abnormally formed rotor of metal results in the magnetically prompting signals of the driven coils to come back in various shapes and sizes. Comparing the two driven coils signals enables the motor control module to find out the approximate position, speed and direction of the drive motor generator rotor. The position sensor is a component of the drive motor generator that is not able to service.

What causes this problem with the Drive Motor "B" Position Sensor Circuit "B" Low

• Defective Drive Motor Generator
• Open or shorted Drive Motor Generator harness
• Bad electrical connection in Drive Motor Generator circuit

1. Drive Motor Generator - A recurrent sign of a problem with your starter is when turning your key to see that nothing is performing. You could hear an engine sound or a loud clanking sound. The starter solenoid frequently induces this problem or a combustive motor or you are dealing with an electrical problem. Regardless, an expired battery could also be causing this problem. In this case, you should find an experienced mechanic to check out the starter, ignition system, and other electrical components, as it could indicate many other problems. Sometime you will turn on the ignition switch and begin hearing the starter activate, but will not hear the motor cranking over. Sometimes, issues related to the starter are basically mechanical by nature. Apparently, the problem could happen due to the gears being connected to the flywheel. This can happen due to stripping the removal of the gear in resistance to the flywheel. Any way possible, the engine will not turn over and you will have to seek an certified mechanic to replace the starter.
2. Motor Position Sensor - You may notice that your car is not speeding up as you expect it to, and it jerks or stalls while trying to pick up speed. It may speed up smoothly, but then it will lose power. On the flip side, your car may suddenly speed up while you are driving, in regards that you did not press on the accelerator. If you notice any of these signs, it’s very likely that you have a problem with the Motor Position Sensor. According to the MPS, it won’t send the right input being set the onboard computer thus won’t be able help the engine in performing efficiently. When the car
   accelerates as you drive, this typically defines how the butterfly valve inside the throttle gets closed up and pops open suddenly as the driver presses on the accelerator. This results in the car giving a fast and sudden burst of speed that occurs because the sensor is incapable of
   determining the closed position of the throttle. Once the TPS begins failing, even partially, you’ll must immediately have it replaced. In replacing the TPS also assists in cleaning out
   relevant trouble codes, and may have to reprogram the software within the new TPS module to match up with all the remaining engine management software. This all relies on an experienced mechanic who is able to give you proper diagnosis, and install the correct replacement part.
3. Motor Control Module - A recurrent issue with the ECM power relay is dealing with no power when the key is inserted. When an ECM power relay fails, it cuts off power to the entire vehicle. A relay that failed will disconnect the dash lights and warning chimes that usually turn on when putting the key into the ignition, and will possibly be unable to start or turn over the vehicle. An engine that does not start or turn over, is also a common symptom of a problem dealing with the ECM power relay. The ECM powers the fuel and ignition systems, these of multiple other engine management performances, out of many car makes and models. If a failure is indicated with the ECM or its relay, the whole engine management system will be kept without power and won’t be able to perform as a result. A bad relay may lead to a cranking vehicle, but without starting, or be unable to crank altogether at periods. A failed ECM power relay can also lead to a in drained battery or dead battery. With a relay that has shorted, this could keep the power on board the computer, even when the vehicle is in turn-off mode. This will give the battery a polluted drain, which will eventually lead it to expire. Avoiding this entire procedure will disable the whole ending management system and the vehicle will stop running. On top of that, if you suspect the ECM power relay may be dealing with a problem, then have an experienced mechanic check out the vehicle.
4. Generator Assembly - The generator may face an issue with dim or flickering lights. If you see any type of flickering or dimming of lights when the car is running, this could signal that a generator is failing to process an abundant supply of power to catch up with the car’s electrical needs.
   The dimming or flickering of lights might happen concurrently with these specific actions while running the car, such as the lights will dim when pressing on the gas pedal, turning up the stereo volume, or another light comes on. This symptom may indicate a generator that is unable catch up with the needs of the car’s electrical system while it runs, and adding on more loads.
5. Drive Motor Output Shaft - The seal that maintains fluid inside the transfer case is important for the vehicle’s transmission to run steadily. When a damaged seal leaks fluid, it reduces the fluid volume that is currently processing inside the transmission, in which fluid pressure is also lost, making it more challenging to shift gears for an automatic or manually switched transmission. The output shaft seal could suddenly break or wear out, which can create sounds that come from beneath the vehicle. In such cases, these sounds are a result of a reduction in lubricants inside the transfer case or metals grinding together. If you notice that your transmission is facing challenges in shifting to higher or lower gears, or you hear sounds rooted from the location where your transmission is installed, you should consider finding an certified mechanic instantly to check out this issue and provide a good solution.

Intrigued by learning of the symptoms to OBD P0C61 code? If so, then you came to the correct place. Our team at PartsAvatar have listed some prevalent symptoms related to this fuel injector issue.

It is important to diagnose this trouble code. These are a few helpful steps that a mechanic can follow to diagnose the issue that activated a stored P0C61 code:

If this recurrently happens with the code, you are bound to hear very loud sounds, such as explosions, coming out from the car’s rear when speeding up. At first, detect the carburetor to make sure the fuel and air combination is correctly in balance. If all conditions are correct, then rigorously survey the distributor cap for signs of cracks or splits, for this can create a backfire. Step forward to the spark plugs and make sure they are cleaned and not damaged, and detect the engine gaskets for any appointed damage, as this is critical in making sure to do a correct gas interchange inside the engine. P0C61 OBD2 makes a survey on a sensor error, as replacing the sensor is insusceptible to solving the undertaking issue. The error is highly possible as the wiring to the sensor itself causes a result of the systems, which the sensor is monitoring.
