(See01-02-10 AFTER REPAIR • Are any DTCs present? Yes Go to the applicable DTC inspection. No Troubleshooting completed. STEP INSPECTION ACTION DTC P2101 Throttle actuator circuit range/performance DETECTION CONDITION • If the PCM detects any of the following conditions, the PCM determines that the throttle circuit has a malfunction. significant. — Voltage from drive-by-wire-relay is too high or too low — PCM detects large voltage difference between the drive-by-wire-relay and the main relay — PCM internal malfunction Diagnostic support note • This is a continuous monitor. • MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA is available. • DTCs are stored in PCM memory. POSSIBLE CAUSE • Drive-by-wire-relay and related circuit malfunction • Main relay and related circuit malfunction • Throttle position sensor No.1 and related circuit malfunction • Throttle position sensor No.2 and related circuit malfunction • PCM malfunction STEP INSPECTION ACTION 1 VERIFY FREEZE FRAME DATA HAS BEEN • Has the FREEZE FRAME DATA been recorded? Yes Go to the next step. No Record FREEZE FRAME DATA on the repair order, then go 2 VERIFY RELATED REPAIR INFORMATION • Check for related Service Bulletins and/or on- line repair information availability. • Is any related repair information available? Yes Perform the repair or diagnosis according to the available • If the vehicle is not repaired, go to the next step.
