Got my ThinkDiag2 and hooked it up. Here are my results:
Is that 0.5deg of slop concerning? Is it causing a fault when it goes over some threshold? Any suggestions for next steps? My ideas are to follow the service manual and check ground and voltage at the camshaft and crankshaft sensors and PCM and try a replacement crankshaft sensor. I noticed the sensors look the same besides how they are mounted, so that makes me wonder if replacement crankshaft sensors have the same issues as the camshaft sensor.
- Installed an Echlin sensor since I heard good things about theirs, but got the same code so I swapped back to OEM a few days ago.
- Today ThinkDiag2 showed a Cam Crank Difference of 5.5deg at idle that fluctuated up to 6.0deg while driving. Learned was 0.8deg.
- Rotated OPDA to get a live reading around 0.1deg, set to relearn, and cleared my P0344 code.
- Live data showed Difference going between 0.0 and 0.5deg and Learned set to 0deg. Hit the gas on a test drive and went into limp mode with P0344 again. Live data showed that Difference froze at 0.5deg and Cam Sync State changed from In Sync to Out Of Sync.
