I have an 88 crx so with a full 91 si harness and the Harness custom built by one of our members for the dohc zc. I'm trowing a code 3 and 5. Both are for the map sensor. 1 for the vacuum and 1 for the sensor on a pm6 ecu. My question is can 1 trigger the other or am.I just screwed?

 

Check the wiring at the MAP sensor. Make sure it's plugged in. You may just have a bad MAP sensor, which should be an easy replacement. Shoot, I bought a GM 3 Bar MAP sensor for $20. Should be able to find a stocker for that price.

 

Price isn't the issue. Me needing it by tomorrow is. already checked craigslist

 

eBay my man. If I didn't need mine I'd mail it to you overnight just to see if it was actually the problem.

Rush jobs are the hardest.
