Alrighty now, nobody’s banning anyone. Play nice everyone.

 

Don, I was preparing to remove the center console this weekend to check the contact values and narrow down the malfunction. Since the the 2 codes prior to the C0550-37 was one for Comb. Switch Bias level out of range and brake switch. I will monitor it the next 500 miles this week to see if anything intermittent happens. I appreciate all the help from everyone on this issue.

 

The yaw sensor is actually under the passenger seat left front corner. Just behind the front seat rail support.

 

Thanks Don. That would be much easier to get to.
If anyone is interested, this was the lower ECM connection after 3 cleanings to get the oil out. It took 6 cleanings.

Sorry about the picture quality. My iphone was at work and I had to use a flip phone.

 

Update: After 1200 miles of problem free driving, I believe that I can consider this issue resolved. No computer replacement, just the oil pressure sending unit and clean and properly connected computer connections.

 

I'm having the exact same issue. Same codes and symptoms. Thanks for giving me a direction to go in. As far as cleaning connections, was it just the ECM that needed cleaning? This is my only non-Japanese vehicle so the wiring and computers are very different from what I'm used to

 

Please start a new thread. I am not going to read 6 pages to find out what the "exact" problem is.
