How to service the MAP Sensor on Chevrolet Tahoe?

The first step to servicing a manifold absolute pressure (MAP) sensor involves removing the sight shield fasteners from the Intake Manifold while separating the shield. You need to start by detaching the MAP Sensor electrical connector before disconnecting the sensor from the Intake Manifold. Engineers should apply a thin layer of clean engine oil to the sensor seal right before MAP Sensor installation. Insert the MAP Sensor into the retainer through downward pressure before connecting the MAP Sensor electrical connector. Tighten the fasteners on the Intake Manifold sight shield until they reach 10 n.m (89 lb in).

Chevrolet Tahoe has a MAP Sensor that assist in measuring the positive air pressure that enters the intake manifold for the engine, with real-time information to the ECU for fuel adjustment. In fuel-injected engines the operation of the MAP Sensor is to help in calculating the air density and in identification of the right air-fuel mixture for burning of fuel and this makes the sensor play a crucial role in the speed density method. As for base engines, they can incorporate either MAP or MAF, but for forced induction engines, both are applied. The others include aiding in on-board diagnostics functions and helping in EGR valve intermittent test, the accurate measuring required for MAP Sensor is relevant in fuel metering and engine performance.
