How much does it cost to fix NOx sensor?
If you have a standard economy vehicle, you can expect to pay anywhere from $120 to $500 for replacing your knock sensor. The parts cost will be anywhere from $65 to $200, while the labor costs will be anywhere from $50 to $350.
How do you know if a NOx sensor is bad?
NOx Sensor Problems Most times, this will be immediately obvious due to the illumination of your ‘Engine Warning’ light in the dashboard cluster, along with symptoms such as unstable idle, juddering/jerking while driving, and excessive fuel consumption.
What does the NoX sensor error code u029d mean?
The NOx sensor error codes described as U029D and U029E mean that the NOx sensor A or NOx sensor B is not communicating with the other control modules in the vehicle. Alternatively A and or B control emission units are called as bank 1 or bank 2. This is not ideal but has a set of simple fixes which we’ll address below.
What does lost communication with NoX sensor a mean?
Lost Communication With NOX Sensor A What does that mean? This is a generic communication system diagnostic trouble code that applies to most OBD-II vehicle makes and models. This code means that the NOX Sensor A (NOXS-A) and other control modules on the vehicle are not communicating with each other.
What causes the u029d code to be active?
If you can access codes from the NOXS-A, then the U029D code is either intermittent or a memory code. If unable to access the NOXS-A, then the U029D code that the other modules are setting is active, and the problem is there now. The most common failure is a circuit fault which causes the loss of power or ground to the nox sensor a.
How much does it cost to diagnose an u029d code?
The cost of diagnosing the U029D code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. The reductant system uses two Nitrogen Oxide (NOx) sensors to monitor the amount of NOx in the engine’s exhaust gas.
