Note. If DTC P0107, P0122 and/or P0450 are set together, Check PCM harness connector "B" terminal No. 1 (Pink/Green wire on Esteem, or Light Green wire on Swift) for an open circuit.
- Connect scan tool to Data Link Connector (DLC). Turn ignition on. Observe throttle valve opening percentage on scan tool. If display reads 2 percent or less, go to next step. If display reading is greater than 2 percent, check for an intermittent problem. Go to INTERMITTENTS in «TROUBLE SHOOTING - NO CODES»(ref-91186) article.
- Turn ignition off. Disconnect TP sensor harness connector. Turn ignition on. Measure voltage between ground and Pink/Green (Esteem) or Light Green (Swift) wire at TP sensor harness connector. Reading should be 4-6 volts. If reading is as specified, go to next step. If reading is not as specified, check wire for an open, short to ground or short to Green/Red (Esteem) or Light Green/Black (Swift) wire. Repair as necessary. If wire is okay, go to next step.
- Measure voltage between ground and Gray (Esteem) or Light Green/White (Swift) wire at TP sensor harness connector. Reading should be 4-6 volts. If reading is as specified, go to next step. If reading is not as specified, check wire for a short to ground and retest system. If wire is okay, replace PCM and retest system.
- Measure resistance between specified TP sensor terminals. (Схема №5) See «TP SENSOR RESISTANCE»(ref-91183-S27916153692002110600000) table. If resistance is not as specified, replace TP sensor. If resistance is as specified, replace PCM. Retest system.
