DTC P0507

DTC P0507

Idle speed control system RPM higher than expected

DETECTION CONDITION

The 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 (PSP switch is off).
NOTE:
- If the atmospheric pressure is less than 72.3 kPa {542 mmHg, 21.3 inHg} or intake air temperature is below -10°C {14°F} , the PCM cancels diagnosis of P0507.

Diagnostic support note

This is a continuous monitor (CCM).
The MIL illuminates if the PCM detects the above malfunction conditions 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 (Mode 2/Mode 12) is available.
The DTC is stored in the PCM memory.

POSSIBLE CAUSE

Vacuum hose misconnection
Electronic throttle control system malfunction
PCM malfunction

DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 12) HAS BEEN RECORDED Has the FREEZE FRAME DATA (Mode 12) been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 12) on the repair order, then go to the next step.
2	VERIFY RELATED SERVICE BULLETINS AVAILABILITY Verify related Service Bulletins availability. Is any related Service Bulletins available?	Yes	Perform the repair or diagnosis according to the available Service Bulletins. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY RELATED PENDING CODE AND STORED DTC Turn the ignition switch off, then to the ON position (Engine off). Verify the PENDING CODE and stored DTC using the M-MDS. Are any DTCs present?	Yes	Go to the applicable DTC troubleshooting. (See DTC TABLE ).
3		No	Go to the next step.
4	INSPECT VACUUM HOSE CONNECTION Visually inspect the vacuum hoses connection. Are the vacuum hoses connecting accurately?	Yes	Go to the next step.
4		No	Reconnect the vacuum hose accurately, then go to Step 6.
5	INSPECT ELECTRONIC THROTTLE CONTROL SYSTEM Turn the ignition switch off. Inspect the following parts: APP sensor (See ACCELERATOR PEDAL POSITION (APP) SENSOR INSPECTION ). TP sensor (See THROTTLE POSITION (TP) SENSOR INSPECTION ). Is there any malfunction?	Yes	Replace the malfunctioning parts according to the inspection results, then go to the next step. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION ). (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION ).
5		No	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 M-MDS. 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. (See PCM REMOVAL/INSTALLATION ).
6		No	Go to the next step.
7	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE ). Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE ).
7		No	DTC troubleshooting completed.
