P015D OBD Error Code: Problem & Solutions

OBD Code P015D - O2 Sensor Delayed Response - Lean to Rich Bank 2 Sensor 1

<<See All OBD Codes

The P015D code can be defined as O2 sensor delayed response – lean to rich bank 2 sensor 1. The powertrain control module or the engine control module would continuously monitor the activity of the heated oxygen sensor. During this period of monitoring the powertrain control module would count the number of times the HO2S would respond from rich to lean and from lean to rich and would add the amount of time it took to complete all the transitions. With the help of this information, the PCM/ECM would be able to determine the average time of all transitions. Now if the average response time would be too slow, then this trouble code would start triggering up.

Willing to learn more about P015D fault code? The major role of the car 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 the powertrain control module detects the failure of the sensor or the information is received from the sensor, then the P015D fault code would start appearing.

 

What causes this problem with the O2 Sensor Delayed Response - Lean to Rich (Bank 2 Sensor 1)?

 

  • Issues with the car oxygen sensor
  • The connectors or the wiring can be burnt, broken, or sometimes may get disconnected
  • There can be defects with the catalytic converter
  • Issue of leakage in the engine exhaust

Replace/Repair These Parts To Fix OBD Code P015D

  1. Oxygen Sensor - The P015D code can also arise due to some issues in Oxygen Sensor. So, it is advised to replace them as soon as possible.
  2. Exhaust System - P015D code does not really end up spoiling your timing belt, but it might also accompany few Exhaust System parts issues. We have best Exhaust Gas related parts with us.
  3. Exhaust Manifold - The P015D code can also arise due to some issues in Exhaust Manifold. So, it is advised to replace them as soon as possible.
  4. Powertrain Control Module - Do you remember when was the last time you got your car Powertrain Control Module checked up? A damaged Powertrain Control Module can cause a lot of issues like displaying P015D code.
  5. Catalytic Converter - Catalytic Converter is an important car part which should never be neglected. May be there is some fault in it due to which P015D code may start flashing.
  6. O2 Sensor Wiring Harness - Is your O2 Sensor Wiring Harness damaged or broken? Don’t worry as we have solutions for all your problems.

  • The car oxygen sensor should be replaced as soon as possible

However, if you face any issue then you can always visit us. We have stocked a wide range of best priced fuel injector, exhaust clamps, injector pump and a lot more to help you out in fixing your car.

Easy Diagnosis Of Engine Error OBD Code P015D

Make sure that you have some main tools like diagnostic scanner, a digital volt/ohmmeter (DVOM), and a reliable vehicle information source for diagnosing P015D fault code. Before you start trying to diagnose this fault code, make sure that you get the engine misfire codes, throttle position sensor codes, manifold air pressure codes, mass air flow sensor codes diagnosed and repaired properly. 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 P015D Code

  • The problem of exhaust leak
  • Oxygen sensor may start failing
  • There can be some defects in the powertrain control module
  • The issue of wiring may arise
