Test Description

WARNING: This page is about a different car, the 2003 GMC Sonoma and 2003 Chevrolet S10 Pickup. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers on the diagnostic procedures.

  1. 8 -  While starting the engine, the MAP sensor should detect any changes in manifold pressure. This test is used to determine if sensor is stuck at a value.
  2. 9 -  A normal MAP sensor will react as quickly to the throttle changes as they can be made. A MAP sensor should not appear to be "lazy" or catch up with the throttle movements.
