(P0211) THROTTLE ACTUATOR STUCK (CONTINUED) 4. TP 1 AND TP 2 BOTH EQUAL 2.5 VOLTS With the ignition on. With the DRB III T , read both TP voltage readings. Are both TP readings stuck at 2.5 volts? Yes >> Check the TP Signal circuits for excessive resistance, a short to each other, or short to the Sensor Ground circuit. Perform POWERTRAIN VERIFICATION TEST - VER 2. No >> Go To 5 5. THROTTLE CONTROL MOTOR 1 CIRCUIT SHORT TO VOLTAGE Turn the ignition off. Disconnect the Throttle Body harness connector. Disconnect the PCM C1 harness connector. Note: Check connectors — Clean/repair as necessary. Measure the voltage of the Throttle Control Motor 1 circuit at the Is the voltage below 1.0 volt? Yes >> Go To 6 No >> Repair the Throttle Control Motor 1 circuit for a short to voltage. Perform POWERTRAIN VERIFICATION TEST - VER 2. 6. THROTTLE CONTROL MOTOR 1 CIRCUIT OPEN Turn the ignition off. Measure the resistance of the Throttle Control Motor 1 circuit from the Is the resistance below 5.0 ohms? Yes >> Go To 7 No >> Repair the Throttle Control Motor 1 circuit for an open. Perform POWERTRAIN VERIFICATION TEST - VER 2. ZH ENGINE - ELECTRICAL DIAGNOSTICS 9 - 297 |
