Error Code P2614: What It Means & What To Do?

<<See All OBD Codes

If you experience engine stalling and not starting or occasional loss of power and acceleration with affected fuel economy and engine misfires, you can suspect a problematic camshaft sensor or circuit that might have malfunctioned, thus indicating OBD code P2614 error in the Powertrain control module.

Error Code P2614 is a very common fault code. The ECM, PCM and many more use the CMP or also known as camshaft position sensor to easily figure out what it should set the timing at. The CMP sensor is an important component, since without knowing what the right timing should be, the computer is useless. OBD code P2614 simply means that the PCM has completely sent a signal to the camshaft position sensor, however it does not receive the right signal that is being returned from the sensor. Since the circuit is a concern, the problem could be in any component of the circuit such as PCM, wiring and sensor itself.

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

• Broken, shorted or grounded connector or wire in the route circuit
• Faulty Powertrain Control Module
• Circuit and damaged wirings open
• Faulty crankshaft position sensor
• Dead or weak battery
• Starting system circuit
• Faulty starter motor
• Camshaft position sensor electrical connection nay be faulty
• Camshaft position sensor wiring harness short or open
• Faulty camshaft position sensor

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. 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.
3. 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.
4. 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!
5. Fuel Injector – Bad fuel injectors can cause starting issues, poor idles and affected performance. Thus, the replacements are in order. Buy new fuel injectors now!
6. Camshaft Position Sensor – If the camshaft position sensor goes bad, the set gear may lock in place. This means that the driver will have trouble shifting to another gear, although even might not be able to shift at all. Thus, replace it now!

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 P2614 here:

Common Symptoms

• The Check Engine Light will come on
• The vehicle may not start, or may be difficult to start
• The vehicle may idle rough or stall
• The vehicle may misfire
• There may be a loss of power while driving

Here are some ways with the help of which you will be able to correct the OBD Code P2614.

• Camshaft position sensor replacement
• Fuel injector replacement
• Damaged and corroded wiring and connector replacement
• PCM repair and reprogramming

Here are some steps which you should follow in order to diagnose this fault code P2614:

At the camshaft position sensor, make sure it is plugged in and firmly seated. Also, inspect the wiring harness to look for damage, such as from recent engine repairs, aftermarket installations, impact damage, or rodent damage.

Disconnect the sensor and measure resistance. An open-circuit, or short-circuit, at this point would tell you that the sensor itself is at fault. The proper way to do this would be with a digital oscilloscope, but you can get a rough estimation of CMP sensor function by putting your DVOM in AC V mode. When cranking, one will be able to see at least 20 mV.

Disconnect the ECM and CMP connectors, and put a short pin across the terminals of the CMP connection. Use a small paperclip or wire for this.

Check for resistance in the circuit itself from the ECM side. With the short pin in place, you should read less than 0.1 ohm. The ECU will be unable to detect the signal if it is any higher. Also check for a broken wire or corrosion somewhere in the circuit.

Check for open circuit by removing the short pin. Suspect a short circuit in case of some amount of resistance. Water in an intermediary connector could easily be the cause of short-circuit.

Check for short-to-ground by taking one of the leads and connecting it to body-ground or the negative battery terminal. You should read an open circuit, any unintentional connection to ground could distort or weaken the signal.

In case no problems can be found in the CMP sensor or its wiring, it may be that P2614 is simply auxiliary fault codes. The primary problems may include a jumped timing belt, faulty crankshaft position sensor signal or circuit, or engine misfire.

Common Mistakes When Diagnosing the P2614 Code

It is important to inspect the wiring and connectors to rule them out as the cause of the problem before directly jumping to the camshaft sensor for replacement. This is the most common mistake when diagnosing the P2614 trouble code.

Another mistake that is made during the diagnostic procedure is neglecting to consider a misfiring problem or a crankshaft sensor problem as possible sources of the P2614 trouble code.
