Is the measured resistance within specifications?
YES : --> Go to "Check ECM/PCM" procedure.

NO : --> Check TPS for contamination, deterioration, or damage. Substitute with a known-good TPS and check for proper operation. If the problem is corrected, replace TPS and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

Check ECM/PCM.
1. Ignition "OFF"
2. Connect the scantool and select "Simulation SCAN" in the menu.
3. Connect channel A of scantool with terminal 1 of TPS harness connector, and key "ON".
4. Simulate voltage at signal line.

5. Is TPS signal value changed according to simulation voltage?
  YES : --> Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  
  NO : --> Substitute with a known-good ECM/PCM and check for proper operation.
  
  --> If the problem is corrected, replace ECM/PCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
