Pinpoint Tests D: Crankshaft Position (CKP) 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:

CKP sensor (6C315)
harness circuits: CKP, SIGRTN and VREF
