DTC P0507:00 [L8, LF, L5]

id010242705100

DTC P0507:00

Idle air 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).

Note

•  If intake air temperature is –10 °C {14 °F} or less, the PCM cancels diagnosis of P0507.

Diagnostic support note

•  This is a continuous monitor (CCM).

•  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 first drive cycle.

•  FREEZE FRAME DATA is available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  Drive-by-wire control malfunction

•  Vacuum hose misconnection

•  PCM malfunction

Diagnostic procedure

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.
1		No	Record the FREEZE FRAME on the repair order, then go to the next step.
2	VERIFY RELATED SERVICE 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.
2		No	Go to the next step.
3	VERIFY RELATED PENDING OR STORED DTCS • Switch the ignition to off, then to the ON (Engine off). • Verify PENDING CODE or stored DTCs using the M-MDS. • Are other DTCs present?	Yes	Repair the applicable DTCs. (See DTC TABLE [L8, LF, L5].)
3		No	Go to the next step.
4	VERIFY DRIVE-BY-WIRE CONTROL SYSTEM OPERATION • Perform the TP sweep inspection. (See ENGINE CONTROL SYSTEM OPERATION INSPECTION [L8, LF, L5].) • Does the drive-by-wire control system work properly?	Yes	Go to the next step.
4		No	Repair or replace malfunctioning part according to inspection result. Then go to Step 6.
5	INSPECT VACUUM HOSE CONNECTION • Are vacuum hoses connecting accurately?	Yes	Go to the next step.
5		No	Reconnect vacuum hose accurately, then go to the next step.
6	VERIFY TROUBLESHOOTING OF DTC P0507:00 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 seconds or more. • Is the PENDING CODE for this DTC present?	Yes	Replace this PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L8, LF, L5].)
6		No	Go to the next step.
7	VERIFY AFTER REPAIR PROCEDURE • Perform “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [L8, LF, L5].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [L8, LF, L5].)
7		No	Troubleshooting completed.
