Ls vtec turbo don't rev.
hi guys, I'm having problems with my engine sputtering and sometimes dying when press the gas. No CEL whatsoever, I find low voltage 3.98v at d17 pin on the ECU which is for the MAP sensor and it should be at 5.0v.
change a stock map and made a base map and the car still the same or worst.
This is a bad ECU?

Re: Ls vtec turbo don't rev.
did you swap a good map sensor in?
have you done anything with the harness? The MAP sensor plug is the same as other plugs around it
make sure you have the right plug on the right sensor

Re: Ls vtec turbo don't rev.
yes, I put a stock one to verify the Omni wasn't the culprit (made a base map) but still the same.
I don't touch the harness since I put the engine together like 3 years ago.
Man, this is the problem I have the right plug but with low voltage at one pin and the ECU won't throw any code.
Also I have the same voltage readings at the MAP plug and the ECU d17 and d21.
