P002A - OBD Trouble Code

<<See All OBD Codes

A sudden drop in the fuel efficiency and the engine performance may be an indication of problem with the camshaft, thus indicating OBD Code P002A Error where “B” is an indicative of problem with Camshaft Profile Circuit Control.

Therefore, OBD Code P002A - “B” error refers to the timing discrepancy between the crankshaft and exhaust camshaft.

OBD-II Code Decreased engine performance is defined as a "B" Camshaft Profile Control Circuit/Open.

The engine control module (PCM) uses a signal from the camshaft position sensor to determine the proper time to fire the fuel injector and ignite the spark plug. The PCM compares this signal to the signal from the crankshaft to determine if the engine is timed properly. Newer vehicles use a variable timing system to adjust the timing of the camshaft in relation to the crankshaft to increase fuel efficiency and performance. If the Camshaft is not in the proper position relative to the crankshaft, the PCM will set code P002A.

What causes this problem with the Camshaft Profile Circuit Control?

• Reduced engine oil levels
• Use of incorrect/contaminated engine oil
• Ill-timed Car Engine
• Damaged/stretched timing chain/belt
• Faulty Camshaft/Crankshaft Sensor
• Faulty wiring/harness to the camshaft and/or crankshaft sensors
• Problem with the PCM/ECM (Powertrain Control Module)
• Stuck/Damaged Valve

1. Camshaft & Parts - The main indicative of OBD Code P002A is a faulty exhaust camshaft. Immediate replacement is required. Visit us today to get all camshaft related replacement parts.
2. Crankshaft & Parts - Damaged/faulty crankshaft directly affects the engine power and output. Buy quality crankshaft replacement parts now.
3. Powertrain Control Module - P002A error code also relates to problems with the powertrain. Find all the Powertrain related parts with us.
4. Engine Timing Cover - The timing cover is an essential component designed to protect the timing belt, timing chain or cam belt of your car. Replace old timing covers today.
5. Timing Belt And Pulleys - Another reason for P002A error is the faulty engine timing belt and its parts. To remove the error, immediate replacement is in order.
6. Exhaust Valve - There can be issues with the exhaust valve thus resulting in that check engine line on indication. Replace old seal valves now.
7. Diagnostic Tool - In order to detect the error, one needs high grade diagnostic tools. Visit us today to grab amazing deals.

This fault may cause reduced power, the engine may run rough, or the engine may crank but not start. There is typically an illuminated Check Engine light as well. Visit Parts Avatar Canada to get genuine replacement parts and performance parts for your vehicle. This error may also indicate problems that will likely affect:

Common Symptoms

• Check Engine Light will illuminate indicating error P002A code
• Engine lacks power and reduces performance
• Increased fuel consumption due to problem in fuel delivery system
• Unusual throttle response and stalling

Some of the common fixes for the problems in the OBD Code P002A for all makes and models are as follows;

• Use clean engine oil and the one with proper specification for the vehicle
• Remove accessories needed to gain access to engine timing cover
• Inspect timing belt, timing covers and pulleys for needed parts and reinstall after inspection
• Check for cooling system leaks and check for proper engine operation and engine timing
• Replace camshaft sensor and/or crankshaft sensor and also check for its wiring
• Check if the replacement of PCM(Powertrain Control Module) is required
• Replace stuck valve

Following are the steps to be followed for a proper diagnosis of OBD Code P002A; 

• A technician begins by hooking the vehicle to an OBD-II scanner to verify that the code is present, and check for other codes.
• The freeze frame data along with current data is recorded, and the codes are then cleared to see if they reoccur.
• Visual inspection of the wiring and connectors to check for loose connections, corrosion, or shorts is done.
• A specialized tool may be used to test the camshaft sensor. Other tests of the crankshaft and camshaft components may help pinpoint the problem, as well as inspection of the timing chain or timing belt.
• If there is any physical problem with the timing belt this could cause the timing to go off far enough to trigger a code P002A.

Common Mistakes When Diagnosing OBD Code P002A

Most of the time the camshaft is immediately replaced without analyzing the problem as per the OBD code error. Thus, proper scan tools need to be used to check for the real cause of the problem that may be ECM, wiring issues, fuel system problems and many more parts other than the camshaft only. Thus, proper evaluation and remedy is advisable.
