What does p2189 mean on a car engine?
NOTE #1: Code P2189 indicates an issue with the air/fuel mixture when the engine is running at idle; issues with the air/fuel mixture when the engine is running above idling speed is generally indicated by other codes, some of which may be manufacturer specific.
What causes a p2187 intake air leak?
P2187 Possible Causes Intake air leaks Faulty front heated oxygen sensor Ignition misfiring Faulty fuel injectors Incorrect fuel pressure Lack of fuel Faulty Mass Air Flow (MAF) sensor Incorrect Positive Crankcase Ventilation (PCV) hose connection
What to do if you get a p2187 code?
Start by checking the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. The cost to diagnose the P2187 code is 1.0 hour of labor.
Why is my p2189 system too lean at idle?
Additional codes to pinpoint cause of original P2189 code Air leaking into the intake manifold downstream from the Mass Airflow sensor due to the manifold itself, vacuum hoses off or cracked, leak MAP sensor, Leak at turbo bypass or it’s stuck open, power brake booster hose, or a leak in the EVAP system hoses.
What is too lean at idle OBD code?
This is an ambiguous code in of itself. It can be a tough code to crack without a diagnostic strategy. During the last two starts, the engine management computer has recognized a problem with the fuel mixture at an idle. It appears that the fuel mixture is too lean (too much air and not enough fuel) at an idle.
Is the DTC code too lean at idle generic?
It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may be slightly different depending on the model. This is an ambiguous code in of itself. It can be a tough code to crack without a diagnostic strategy.
