Pinpoint Test AX: Intake Throttle: 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: TACM+, TACM-, TP, SIGRTN and VREF
intake throttle actuator (9E926)
