CHEVROLET CORVETTE SENSOR PROBLEM

1988 Chevrolet Corvette • V8 • 69,000 miles

My 1988 corvette keeps throwing a code 34 about every 4th start. I cleaned the throttle body and it still did it. What now?

Have you checked the MAP sensor? 34 -- MAP sensor(voltage low) / MAF sensor

Yes I did and replaced it with a new not reman. That is when I had a code 33 now it's the 34. Getting soooo frustrated

So the voltage was high and now it's low. Have you checked wiring to the sensor?
