3. CHECK THE THROTTLE POSITION SENSOR (TPS) POWER SUPPLY CIRCUIT • Turn ignition switch on. • Check TPS supply voltage between TPS terminal 3 and ground in the TPS electrical connector E-027. • Approximately 5 V should exist. Is the check result normal? Yes >> Go to step 8. No >> Go to the next step. 4. CHECK THE TPS POWER SUPPLY CIRCUIT • Turn ignition switch off. • Disconnect ECM harness connector. • Check harness continuity between TPS terminal 3 and ECM terminal 32. • Continuity should exist. Is the check result normal? Yes >> Go to the next step. No >> Repair or replace circuit for an open. 5. CHECK THE TPS AND THE ACCELERATOR PEDAL POSITION (APP) SENSOR POWER SUPPLY CIRCUIT • Check harness for short to power and short to ground between following terminals. ECM TERMINAL TPS/APS TERMINAL 32 TPS terminal 3 32 APP sensor terminal 3 33 APP sensor terminal 6 Is the check result normal? Yes >> Go to the next step.
