Discuss the causes and fixes for P0101 2011 Nissan Pathfinder OBDII Code
-
2011 Pathfinder has CHRONIC P101 codes with varying descriptions, including Range/Performance and Open Circuit. Sensor was replaced (allegedly) at shop with New Sensor for $169.00. Next Service Engine Soon light two days later. I replaced air filter (twice) but no fix. The vehicle displays NO SyMPTOMS. It runs fine, starts easily, and gets good mileage with no smoke and no oil consumption. With the code reading: MAF OPEN CIRCUIT the engine will stumble if I unplug the MAF Sensor. Therefore, the Circuit is NOT Open, even though that is the read-out.
-
There is a factory service bulletin that recommend reprogramming the Engine Control Module (ECM) (See "Tech Notes" above for bulletin number). If you have already replaced the MAF, then your next step is to reprogram the ECM. Unfortunately only the dealer is able to get the latest ECM program.
-
How much does the dealer typically charge to do the reprogramming? And is it worth it other then to prevent the service engine light from coming on? I have the same reoccurring issue.
-
The price varies per dealer, but they will charge at least 1.0 hours of labor (Around $150). For the P0101 code, if you have already replaced the MAF, your next step is to reprogram the ECM. If you have no other symptoms, you may no need to reprogram the ECM.
