M2 - Did Engine Achieve Greater Than 2000 RPM



- During the Wide Open Throttle (WOT) in the Dynamic Response Test, did the engine achieve greater than 2000 rpm?

Yes -- Replace Powertrain Control Module (PCM). Rerun quick test. Quick Test Appendix (Detailed Testing Instructions)

No -- Check for conditions that would prevent engine from achieving greater than 2000 rpm (binding throttle linkage, etc.). If OK, return to Diagnostic Routines for other possible causes of the vehicle's driveability symptoms. Symptom Related Diagnostic Procedures
