DTC P0507 | Idle control system RPM higher than expected
--- | ---
DETECTION CONDITION | • Actual idle speed is higher than expected by 200 rpm for 14 s when the brake pedal is depressed (brake switch is on) and steering wheel is held straight ahead (power steering pressure switch is off). Note • If the atmospheric pressure is less than 72.3 kPa {542 mmHg, 21.3 inHg} or the intake air temperature is below -10 °C {14 °F}, the PCM cancels diagnosis of P0507. Diagnostic support note • This is a continuous monitor (CCM). • MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. • PENDING CODE is available 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 | • Electronic throttle control system malfunction • Vacuum hose misconnection • PCM malfunction

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available? | Yes | Perform repair or diagnosis according to the available Service information. If the vehicle is not repaired, go to the next step.

No | Reconnect the vacuum hoses correctly, then go to step 6.
5 | INSPECT ELECTRONIC THROTTLE CONTROL SYSTEM MALFUNCTION • Inspect the following parts: - APP sensor (See ACCELERATOR PEDAL POSITION (APP) SENSOR INSPECTION [L3 Turbo].) - TP sensor (See THROTTLE POSITION (TP) SENSOR INSPECTION [L3 Turbo].) • Are they normal? | Yes | Go to the next step.
No | Replace the necessary parts, then go to the next step.
6 | VERIFY TROUBLESHOOTING OF DTC P0507 COMPLETED • Make sure to reconnect all disconnected connectors. • Start the engine. • Clear the DTC from the PCM memory using the WDS or equivalent. • Depress the brake pedal for 14 s or more. • Is the PENDING CODE for this DTC present? | Yes | Replace the PCM, then go to the next step.
No | Go to the next step.
7 | VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [L3 Turbo].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [L3 Turbo].)
No | Troubleshooting completed.
