OBD Code P014B is stored when the powertrain control module (PCM) detects a delayed response time from the downstream (or post catalytic converter) oxygen (O2) sensor or circuit for engine bank two.
How do I fix code p015b?
Zitat von Youtube: In order to prevent leaking get some gasoline put it in a cup and then dip the new fuel injector into it. So the seals may get wet with gasoline.
What does code P013B mean?
Diagnostic trouble code (DTC) P013B stands for “O2 Sensor Slow Response – Lean to Rich (Bank 1, Sensor 2).” This code is logged once the powertrain control module (PCM) detects that oxygen sensor 2 in bank 1 of the engine is taking longer than expected to switch from rich (a higher output voltage) to lean (a lower …
What does code P014C mean?
The engine control module (PCM) is constantly adjusting the amount of fuel delivered to the engine based off of the oxygen sensor’s signal. If the PCM does not see the Oxygen sensor reading constantly changing with the fuel adjustment, it will set code P014C.
What causes P015B?
P015B code means that your vehicle’s powertrain control module (PCM) has detected a delayed response time from the upstream oxygen sensor on Bank 1. Usually, a slight decrease in fuel economy will be the result, along with an MIL light.
What causes O2 sensor slow response?
The slow response of an O2 sensor may be due to a sensor that is just getting old and over time may get contaminated with time with carbon and other contaminants that deteriorate the sensor over time.
How is P0171 diagnosed?
How does a mechanic diagnose the P0171 code?
- Assuming that no other trouble codes exist, a mechanic may diagnose the P0171 code by checking the engine for vacuum leaks with a vacuum gauge. …
- The fuel pressure sensor and MAF sensor (mass air flow) will also be checked with a fuel pressure gauge.
