Component Inspection
1. Ignition "OFF"
2. Measure resistance between terminals 77 and 78 of the ECM Connector (ECM side)
A. Specification: Approx. 110 - 130 Ohms
3. Is resistance within the specification ?
YES
1) Check for poor connection between ECM 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
NO
1) Check ECM for contamination, deterioration, or damage. Substitute with a known-good ECM and check for proper operation. If the problem is corrected, replace ECM and then go to "Verification of Vehicle Repair" procedure.
CAUTION: It is necessary to perform the TPS adaptation procedure with Scan tool when the throttle body assembly or ECM is replaced.
TPS adaptation procedure
1. Erase previous TPS adaptation value using Scan tool.
2. Ignition "OFF" and then "ON" without cranking. Wait for 10 seconds under enable conditions
Enable conditions : Battery >10V & Intake Air Temp. >5.3 °C (41.5 °F) & 5.3 °C (41.5 °F)
