Measure resistance between High signal terminal and Low signal terminal of PCM connector(PCM side).
Specification : Approx. 110~130Ω
Is resistance within the specification?
 | ▶ Check for poor connection between PCM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "Verification of Vehicle Repair" procedure |
 | ▶ Check ECM for contamination, deterioration, or damage. Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM and then go to "Verification of Vehicle Repair" procedure. |
