Common Infiniti Nissan Issue: Check Engine Light On High Idle

Make: Infiniti | Model example: 2012 Infiniti FX35 | Avg Mileage: 124937 | Job Number: 273626

Repair Issue:

Check Engine Light On High Idle

Cause:

Engine speed exceeded 200 RPM over target idle speed

Customer Concern:

The check engine light (CEL) is on. Incorrect (high) idle speed code P0507.

Test/Procedure:

1. Perform the Accelerator Pedal Released Position Learning procedure. See Related Document below for details.
2. Perform the Throttle Valve Closed Position Learning procedure. See Related Document below for details.
3. Perform the Idle Air Volume Learning procedure. See Related Document below for details. Follow TSB# NTB05-067 and disconnect one or more fuel injectors as necessary to bring the RPM down and perform the Idle Air Volume Learning procedure. In some cases the engine speed is still not low enough even after killing 2 cylinders, in those cases technicians have been able to start the engine in neutral and immediately drop it into drive right after it starts and that has helped to get the RPM lower.
4. If the idle will not relearn, it may be necessary to bring the vehicle to the dealer to have the factory scan tool try going through the relearn procedures.
5. If the problem still occurs, the vehicle may require throttle body replacement.

Tech Tip:

Engine speed at 200 RPM or more over the target idle speed will set this code. There is a TSB (TSB# NTB05-067) concerning this code that refers to disconnecting one or more fuel injectors to bring the RPM down and perform the Idle Air Volume Learning procedure. It often takes disconnecting two injectors to bring the engine RPM low enough for the idle relearn to work. The idle will not relearn if the engine speed is too high. During the relearn procedure, idle relearning actually begins when the engine is started. The TSB refers to using the factory Consult scan tool, but the manual procedure does work if the procedure is followed exactly. The engine and automatic transmission (if equipped) need to be warmed up too – follow the preparation instructions.

Eric’s first experience working on cars was when he purchased his 1970 model Dodge Charger. After graduation, he went to Texas State Technical College in Waco, Texas, earning a certificate in Automotive Technology. Waco Auto Imports then hired him full time to work on Isuzu, Mazda, Subaru, Suzuki, and Daihatsu. Eric later worked at an Isuzu dealer in the big city of Dallas, then gave up big city life and moved back home to Tyler, Texas for 6 years to work. While at Crown Auto, he worked on Isuzu, Subaru, VW, and Kia. He also received his ASE Master Certification, and became an Isuzu and Subaru factory trained technician. In 1999, Eric began work at White Bear Acura, Isuzu and Subaru, in White Bear Lake, Minnesota, where he earned his L1 certificate. A month later, the family pulled up their Texas roots and moved everyone to Minnesota. He has been with Identifix since 2005. Outside of work, Eric enjoys exercising at the local Farrell’s where he instructs classes in the morning, riding 4 wheelers and camping with wife.
