What causes P2187?
What Does P2187 Mean? Combustion engines run most efficiently when they maintain an air-fuel mixture ratio of 14.7 parts air to 1 part fuel. When there are more than 14.7 parts air to 1 part fuel in the air-fuel mixture, a lean condition exists and code P2187 is triggered when this is noticed at idle on bank 1.
How much does it cost to fix P2187?
All in you can be anywhere from ~$300 – $700. If you choose to DIY, we highly encourage you to clear the fault code after going through all of the possible causes and fixing them, this is a common mistake made with the P2187 VW code.
What does engine code P2189 mean?
Trouble code P2189 indicates that the ECM has determined that there is too much air and too little fuel present in the air-fuel ratio during engine idle.
What are the symptoms of a p2187 trouble code?
After the P2187 code incites the Check Engine Light to light up, other symptoms may be present, including: 1 Difficulty starting 2 Fuel odor 3 Irregular idle or missing 4 Whistling noise
Why is the p2187 code leaking into the intake manifold?
Additional codes to pinpoint cause of original P2187 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 causes the p2187 DTC system to lean at idle?
Potential Causes of P2187 DTC. 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.
Is the code p2189 the same as Bank 2?
Code P2189 is the same code but for Bank #2. There is a laundry list of components that could cause this scenario. For the most part the diagnostic procedure is not difficult — just time consuming, unless it is one of the first items checked.
