P2094 - OBD Trouble Code

<<See All OBD Codes

The trouble code P2094 can be explicated as B Camshaft Position Actuator Control Circuit Low Bank 2. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

It is the engine control module which would examine the B camshaft position actuator control circuit. This trouble code would be set by the ECM when the B camshaft position actuator control circuit would not be as per the parameters set by the manufacturer.

What causes this problem with the B Camshaft Position Actuator Control Circuit Low Bank 2?

• Frayed timing belt or chain
• Unusable camshaft variable timing solenoid
• There can be distorted variable valve timing actuator
• The level of engine oil might be less
• Blown fuse or fuse-able link
• There might be misalignment of timing components
• Defective connector
• There can be inoperative wiring
• Broken ECU

1. Engine Control Module - The solenoid might cause a short in the engine control module because of corrosion in the solenoid or the wire running from the solenoid to the ECM harness.
2. Crankshaft Position Sensor - There can be some issues with the Crankshaft Position Sensor due to which you may see P2094 code appearing over and over again. Visit us to buy best quality Crankshaft Position Sensor online.
3. Engine Wiring Connectors - A lot of issues can arise do to defective Engine Wiring Connectors. Did you just see P2094 code flashing? Now you know the reason why it is appearing. Get it inspected and replaced on time.
4. Electronic Control Unit – The ECU power management control module keeps in check the hybrid battery charging functions. If the ECU is faulty, the battery pack will not be able to properly get charged and thus, the ECU might need replacement.
5. Oil Pressure Gauge - If the oil filter is blocked, then it might cause an oil pressure gauge to read high. Then it is essential to replace the filter and then the oil should also be changed. We have best oil pressure gauge with us.
6. Powertrain Control Module - A trouble with the PCM would mean that it is unable to determine the right fuel mixture and would send the car engine either more or less fuel than it requires. Now when the engine gets more, the carbon emission would increase and fuel economy would drop. In case of the opposite, the engine will choke, stutter, and might start stalling sometimes.
7. Diagnostic Tool – Usually any OBD code problem requires deep insight into the problem and high grade tools in order to fix it properly. Thus, buy quality diagnostic tools form us!

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P2094 here:

Common Symptoms

• Illumination in the service engine soon light
• Rugged engine idle
• There might be a decline in the oil pressure
• There might be engine misfiring problems
• Inferior engine performance
• Increased fuel consumption
• Change oil or service soon light can start lighting up

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P2094:

• The ECU should be restored to working order
• Recondition the non-functioning variable valve timing actuator
• Make sure to mend the faulty blown fuse or fuse-able link
• Rehabilitate the defaults in the filter
• The malfunctioning timing belt or chain should be repaired or replaced as per the need
• Carefully adjust the faults in the wiring
• It is necessary to perform proper service of the unsound camshaft variable timing solenoid
• Clean the corrosion from connectors

If you want to easily diagnose this trouble code, then you must follow the steps which are mentioned here as below:

Make sure to consult your vehicle information source for technical service bulletins (TSB) that replicate the code stored, vehicle (year, make, model, and engine), and symptoms exhibited. If you find the appropriate TSB, it may yield helpful diagnostic information. A diagnostic scanner and a digital volt/ohmmeter will be necessary to accurately diagnose a code P2094. A reliable source of vehicle information will also be needed. After that the next step would be to inspect the level of the oil as well as its condition. The proper oil pressure would play a major role in the functioning of this circuit. After that all the components which are within the circuit should be located and then a visual inspection should be performed to inspect the related wiring for obvious faults like scraping, rubbing, bare wires, or burn spots. Then examine the connectors for security, corrosion and defective pins. This process must include all related sensors, constituents and the ECU.

Advanced Steps

• The advanced steps become very vehicle specific and need the appropriate advanced equipment to perform in the right way.
• There would be a need of a digital multimeter and the specific technical references to carry out this procedure.
• Voltage requirements will vary depending upon the specific year, make and model of the vehicle.

Timing Checks

• The timing must be checked using the appropriate test equipment and the settings must be precise for the engine to operate correctly.
• An incorrect timing reading is an indication that essential timing components such as the belt, chain or gears may be worn or damaged.
• If this code is exhibited immediately after a timing belt or chain replacement, then you can suspect misalignment of timing components as the possible cause.

Voltage Checks

• The camshaft and crankshaft sensors are generally supplied with a voltage reference of approximately 5-volts from the electronic control unit.
• If this process identifies the absence of a power source or ground, then there would be a need of continuity testing to check the integrity of the wiring, connectors as well as components.
• Make sure to perform the continuity tests with the power removed from the circuit and the normal readings for wiring and connections should be 0 ohms of resistance.
• Resistance or no continuity would indicate that the wiring might be opened or shorted and thus, it should be restored or repaired properly.

Common Mistakes When Diagnosing The P2094 Code

• Common mistakes while diagnosing this trouble code are unnecessary and expensive replacements which usually happens when one doesn't follow all the steps carefully. In this code usually people replace ECU or sensors without even properly diagnosing it, when in reality the main problem is with the wrong timing alignment or insufficient oil pressure.
• The most common mistake while diagnosing this code is missing out on diagnosing steps which further leads to the expensive and unnecessary replacements. It is always recommended to seek the help of experienced diagnostician to avoid any mistakes.
