Guide To P2616 OBD Error Code Solutions

<<See All OBD Codes

A sudden affect in the engine performance along with occasional engine stalling and not starting may be an indication of problems with the camshaft, thus indicating OBD Code P2616 error where the sensor is emitting higher voltage output than the desired limit.

OBD code P2616 means Camshaft Position Signal Output Circuit High Issue.

The camshaft position sensor sends a signal to the PCM (powertrain control module, also known as ECM or engine control module in other vehicle makes) regarding its position based on how the ‘teeth’ or notches on the camshaft interrupt its magnetic field. The PCM then uses this data to provide the right strategies for the fuel delivery and ignition timing of the engine. If this input is too high than the specified range b y the manufacturer, or otherwise incorrect, the PCM will not have the right amount of information to provide the proper timing for such functions.

What causes this problem with the Camshaft Position Signal Output Circuit High?

• Faulty wiring connection to the cam sensor
• Broken or corroded connections to the sensor or the circuit
• Faulty camshaft position sensor
• Bad wiring connection at PCM
• Defective crankshaft sensor 

1. Engine Control Module – ECM faults are rare but can be a big problem as faulty ECM will cause wrong vehicle operations and can also result in wrong OBD codes getting stored in the system which can also cause misdiagnosis. Thus, replace faulty ECM components now!
2. Electronic Control Unit – The ECU coordinates with the temperature sensor to control the blower fan for keeping the battery temperatures under control. So, replace faulty ECU components now!
3. Fuel Injector - Faulty fuel injector, it will cause rough idles and difficulty in starting. Also, it will affect the fuel economy and engine performance. Fuel injector can also crack or break leading to leakages and should be replaced immediately.
4. Powertrain Control Module – Check for PCM error which might be due to circuit faults that might require complete replacement and reprogramming. Replace it now!
5. Diagnostic Tool - In order to detect the error, one needs high grade diagnostic tools. Visit us today to grab amazing deals.
6. Camshaft Position Sensor – If the camshaft position sensor is at fault, you may notice a weaker performance and slow response time from the engine. You probably won’t be able to go faster and will have a limited acceleration. Not only will you fail to go faster, the vehicle may start to jerk around too. Thus, realise the problem and replace the faulty sensor in time.
7. Ignition Spark Plug – These are the parts to be checked for faults first and replace quickly and are also cheap to replace. Buy and replace with new spark plugs now!

If you want to easily diagnose this fault code P2616, then all you have to do is to follow the steps which are mentioned below:

• Verify the code by hooking the vehicle up to an OBD-II scanner and check for other codes.
• Record the data along with freeze frame data, and the codes are then cleared to see if they reoccur.
• Wiring and connectors to be checked for loose connections, corrosion, or shorts.
• Test the camshaft and crankshaft sensors using specialised tools and also test the components that may help pinpoint the problem, as well as inspection of the timing chain or timing belt.
• If there is a physical problem with the timing belt this could cause the timing to go off far enough to trigger a code P2616.
• Check for errors in the powertrain control module which can be corrected by replacing the PCM and reprogramming it again.
• Always retest the vehicle after every step of diagnosis to avoid any more error codes to get stored.

Common Mistakes When Diagnosing the P2616 Code

Oftentimes the camshaft sensor is repaired and replaced, without checking the timing chain or belt for damage or stretching. Since there are many reasons for the error code P2616, all the components must be examined properly first to avoid any unnecessary changes and increasing the expenses.
