Pinpoint Tests E: Manifold Absolute Pressure (MAP) Sensor: Introduction

NOTE: Regeneration may occur during normal operation. During regeneration, diagnostic procedures may display biased values. If a regeneration occurs during diagnostic procedures, allow the process to complete before continuing diagnostics.

This pinpoint test is intended to diagnose the following:

harness circuits: MAP, SIGRTN, and VREF
MAP sensor (14A464)
MAP/CACT
PCM (12A650)
