Where is a map sensor on a 1998 Chevy Tahoe?
Check for the Manifold Abosolute Pressure (MAP) on top of the intake manifold. In the 5.7 engine it is located right behind trottle body. You have to remove all the intake air duct to get to it. Good luck, Tizo
The MAP sensor is on top and very back of the intake manifold. It has 3 leads marked ground, output, and 5V. I needed to remove the large plastic cover and the smaller flat plastic cover on top of the engine to access it. The MAF sensor is a different part and is located between the air filter and the throttle body.
Tough question,untill you find out whats causing the miss to start with. Could be 1 of these problems making it miss. ( Bad spark plug, plug wire, Bad distributor cap, Injector problem, emission sensor shorted are grounded- O2 sensor / oxygen sensor, Map sensor, vacuum leak, Low engine compression / burnt Valve. ect....
