Error Code P015A: What It Means & What To Do?

<<See All OBD Codes

The OBD P015A fault code can be defined as an O2 sensor delayed response – rich or lean. Are there some faults in your car oxygen sensor? Did your car mechanic just tell you that your car wiring or connectors are burnt, broken or disconnected? Then there are some chances that OBD P015A trouble code would soon appear

Want to learn more about P015A fault code? The main purpose of the oxygen sensor is to measure the content of oxygen in the exhaust gases once the combustion process of the engine has been left. This information can be extremely critical to the PCM’s ability to maintain good overall fuel economy. If any failure is detected by the powertrain control module of the sensor or the information is received from the sensor, then the P015A fault code would start appearing.

What causes this problem with the O2 Sensor Delayed Response - Rich to Lean?

• There can be some defects in the O2 sensor
• The wiring or connectors might be burnt, broken, or sometimes disconnected
• Faults in the catalytic converter
• Some leaks in the car engine exhaust

1. Oxygen Sensor - There can be some issues with the Oxygen Sensor due to which you may see P015A code appearing over and over again. Visit us to buy best quality Oxygen Sensor parts online.
2. Exhaust System - Faulty Exhaust System parts can be the reason why P015A code is flashing. Visit us to purchase top notch Exhaust System parts online.
3. Exhaust Manifold - if there are some issues with the Exhaust Manifold, then you may see P015A code appears over and over again. You can always visit us to buy best quality Exhaust Manifold online.
4. Powertrain Control Module - Are you facing some faults in your Powertrain Control Module? Don’t worry and get them replaced or else P015A code can turn up.
5. Catalytic Converter - Common cause behind this P015A error code can be some fault in Catalytic Converter. So, it will be a good decision to replace them now.
6. O2 Sensor Wiring Harness - Timing Chain is perfectly fine but still but having that trouble code P015A flashing? In such a situation your O2 Sensor Wiring Harness might be faulty. Why don’t you think of getting that replaced?

You must have some main tools like diagnostic scanner, a digital volt/ohmmeter (DVOM), and a reliable vehicle information source for diagnosing P015A fault code. Before you start trying to diagnose this fault code, make sure that you get the following codes diagnosed and repaired properly:

• engine misfire codes
• throttle position sensor codes
• manifold air pressure codes
• mass air flow sensor codes

A car engine which would not run properly would cause all sorts of codes to be stored. The technicians who are professionals should first of all do a visual inspection of system wiring harnesses and connectors. The main focus should be on the harnesses that are routed near hot exhaust pipes and manifolds, as well as those that are routed near sharp edges like the ones found on exhaust shields. The technical service bulletins or the TSB should be searched in your vehicle information. If the one is found which would match the symptoms as well as codes presented by the vehicle in question, then it would very likely aid you in your diagnosis. The listings of TSB are compiled from thousands of successful repairs.

Common Mistakes When Diagnosing the P015A Code

• Leakage in the exhaust
• Oxygen sensor may start failing
• There can be some defects in the powertrain control module
• Issues with the wiring
