Código de avería P0159 – This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model. This involves the rear oxygen sensor on the passenger side. Bank 2 is the side of the engine that does not contain cylinder #1. Sensor #2 is the second sensor downstream from the engine. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.

Causas del código P0159
Este código puede estar relacionado con diferentes fallos en el sistema.
Solución del código P0159
The simplest thing to do is to reset the code and see if it comes back. If the code comes back, the problem is more than likely the rear passenger side oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions: Check and fix any exhaust leaks Check for wiring problems (shorted, frayed wires) Check the frequency and amplitude of the oxygen sensor (advanced) Check for a deteriorating / contaminated oxygen sensor, replace if necessary Check for inlet air leaks Check the MAF sensor for proper operation
