Guide To P0022 OBD Error Code Solutions

<<See All OBD Codes

If you notice a faulty camshaft phaser, problems in the overall oil flow, variable camshaft timing as well as the oil control valve getting stuck in the open position, then there is a major possibility that you are dealing with the OBD Code P0022 with your vehicle.

The P0022 is a OBD II trouble code which occurs due to some issues in the Bank 2’s intake camshaft timing and it is delayed than what PCM commands it to be. It can result at the time of advancing or retarding phase of the camshaft timing. The “A” camshaft refers to the intake, front or the left camshaft.

This code generally activates the Check Engine Light of the vehicle and it involves some other symptoms as well like hard starting, acceleration, bad idle and low fuel mileage and black smoke may

start emitting out of the tailpipe.

What causes this problem with the "A" Camshaft Position - Timing Over-Retarded?

• The Variable Camshaft Timing as well as the oil control valve may get stuck in the open position
• The camshaft phaser might get damaged and would stick in the retarded position
• The oil flow problems to the VCT piston and phaser can also cause this issue

1. Oil Control Valve - P0022 error code also relates to problems with the Oil Control Valve. Find all the Oil Control Valve related parts with us.
2. Electromagnetic Sensors - Faulty Electromagnetic Sensors are the reasons for the error P0022. Visit us and replace them immediately.
3. Crankshaft - Any problem in the crankshaft with directly hamper the engines performance. Buy quality crankshaft replacement parts now.
4. Powertrain Control Module - P0022 error code also relates to problems with the PCM if there is any issue with the sensor or electrical connection causing problems with receiving proper signal. Find all the Powertrain related parts with us.

Some of the most common symptoms that indicate the P0022 error code are listed below;

Common Symptoms

• The check engine light may start appearing due to the ECM
• hard start or hesitation on acceleration by the car engine
• The fuel mileage may start decreasing and the engine may blow black smoke out of the tailpipe
• Excessive fumes may start emitting from the engine

• Try to reset the fault codes and perform a road test
• You can use proper oil viscosity for the engine and the replace the oil and filter
• The other step is to replace to repair the wiring or connection to the camshaft oil control valve
• The camshaft oil control valve for the bank 2 intake camshaft should be replaced
• Then you must carefully check the timing chain alignment and cam phasers for damage

Buy top notch replacement parts for all makes and model like Mazda, BMW, Nissan, Audi, etc. and from top brands like Denso, Bosch and many more. We also have high grade harness, camshaft, Engine control module and many more.

If you want to monitor the crankshaft and camshaft positions, then you do that easily with electromagnetic sensors. Relief holes in camshaft and crankshaft drive gears are utilized by these sensors to provide signal interruption of the electromagnetic field. The interruptions in the electromagnetic field as square waveform patterns are seen by the PCM which represent varying degrees of voltage. Electromagnetic resistance is used to create these variations in voltage in the 5-volt circuit

There are some manufacturers who use multiple crankshaft sensors to feed separate data streams to the power control module. Input for engine ignition and fuel injection timing is provided from these data streams. Engines that have multiple camshafts use a camshaft sensor for each camshaft. Other automakers use notches cut into shafts or nodules that are permanently attached to interrupt the electromagnetic field

Generally, the notches or nodules are situated near the rear or middle of the shaft, which depends upon sensor placement. The crankshaft sensor on top of the transmission bell-housing can be placed and crankshaft position from interrupter holes in the flex plate should be read. Do a proper diagnosis to make sure that all engine timing indicators are properly aligned. Make sure that timing marks are aligned, test belt or chain deflection by using manufacturer’s specifications. Test the VVT (Variable Valve Timing) or VCT solenoids and circuitry if timing components prove to be properly aligned. Electrical wiring and connectors are more prone to fail than sensors, especially where oil or other corrosive fluids are present. You can diagnose this code using several tools. To perform a successful diagnosis, you can use an OBD-II scanner, a digital volt/ohmmeter and an oscilloscope.

Common Mistakes When Diagnosing the P0022 Code

You can follow these simple steps to prevent mistakes:

• Before you start attempting any sort of repairs, you must verify the failure carefully
• The viscosity should be of correct type as well as clean
• If you want to prevent any diagnose, then you must follow the pinpoint test step by step
• Make sure that your replace the parts after visual testing and pinpoint
