P0344 Jeep Error Code: Comprehensive Understanding and Troubleshooting Guide

Hey everyone, it’s been a while. Unfortunately, it’s been hard to get some videos up with a lot of things going on, but I’m hoping to get more out soon. Today, I want to share an interesting problem I encountered with a 2008 JK Wrangler, which had come in with a p0344 camshaft position sensor intermittent signal.

When the car arrived, the engine light was constantly on, and I couldn’t clear the code. After checking the sensor’s signals and confirming they were all good, I looked into the connection between the sensor and the PCM, suspecting a bad connection. I discovered a significant difference in signal width compared to the known good signal from the Pico library.

Wanting to ensure the timing was correct, I analyzed the cam and crank signals, which appeared good without any reference. However, comparing them to a known good signal revealed the actual issue: the width of the cam sensor signal was not sufficient for the computer to recognize it properly, potentially causing timing and ignition issues.

To determine the cause, I sought advice from automotive groups and learned about the importance of setting the air gap when installing the cam sensor. I realized that adjusting the sensor’s position to achieve the right air gap could potentially resolve the issue.

I proceeded to raise the sensor slightly to reduce the gap, resulting in a signal width close to the known good signal. After clearing the codes and restarting the car, the engine light went out, confirming that the issue was resolved.

Ultimately, this experience highlighted the value of seeking advice and the importance of having a network to rely on when encountering unfamiliar problems. I hope this insight can help others facing similar issues with camshaft position sensors. Thanks for watching, and see you next time!

What was the issue with the 2008 JK Wrangler?

The 2008 JK Wrangler had a p0344 camshaft position sensor intermittent signal issue. The engine light was constantly on, and the code couldn’t be cleared.

How was the issue resolved?

Upon inspection, it was found that the signal from the camshaft position sensor was not reaching the PCM properly due to the width of the signal. Adjusting the air gap of the cam sensor fixed the issue. The sensor was raised up and tightened to achieve a signal width close to the known good signal, which ultimately resolved the problem.

Where did the solution come from?

The solution was derived from reaching out to automotive experts in online groups, specifically the Automotive Insight Network and Mario’s Super Mario’s group on Facebook. A member of the group suggested that the air gap of the cam sensor might be causing the issue, leading to the successful resolution of the problem.
