My car is throwing codes again. I have a 96 coupe. I am now throwing a vtec oil pressure switch code. It usually comes on when I'm in 3rd gear around 4,000 rpm. And also I started throwing a primary o2 sensor code. Any Info on this????

 

Check you oil level? What o2 code is it? Running to lean or to rich either one will throw a code...what mods do you have?

 

need more info

 

I know in GM's the PCM will set off the SES light when there is a transition time fault in the O2 sensor. That means that the transition from lean to stioch isn't going as fast as it should, the PCM/ECU counts how many times this transitions occurs and if it doesn't reach a certain number after a certain amount of time it'll trigger the SES light. In either case, you'll just have to get the exact code so you know what O2 sensor is faulty and replace it.

 

if its an o2 sensor code, guess what you need a new o2 sensor. They usually go bad sometimes. Find out which code it is (the number), and tell us so we can help you out more.
