What to do about a p2bac NOx exceedance?
Diagnose and repair the O2 sensor code and the P2BAC will literally disappear. Most late model diesel powered vehicles are equipped with DPF systems that reduce soot particles and the resultant black smoke. The DPF is part of the exhaust system and it is equipped with pressure sensors that are monitored by the powertrain control module (PCM).
How much does it cost to fix a p2baa code?
The cost of diagnosing the P2BAA code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When to deactivate the p2bac in a catalytic converter?
When the PCM detects a level of exhaust pressure that is indicative of an unacceptably high level of NOx (in the DPF, NOx trap, or catalytic converter), the EGR system will be deactivated in order to reduce stress on the affected component and diminish exhaust pressure. In this case, the P2BAC will be stored.
Can a p2bac be repaired on an O2 sensor?
In these vehicles, the P2BAC usually accompanies an O2 sensor code. Diagnose and repair the O2 sensor code and the P2BAC will literally disappear.
The cost of diagnosing the P2BAA code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
Where is the second NoX sensor located in the ECM?
The second NOx sensor is located in the DPF that monitors NOx levels exiting the DPF. The ECM varies the amount of reductant added by varying the reductant injector duty cycle in response to changes in engine exhaust out NOx levels. Need more information on how to fix the P2BAA code?
How can you tell if your car has a p2baa code?
Check 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. How much do you know about cars? The cost of diagnosing the P2BAA code is 1.0 hour of labor.
