What code is P0051?
Diagnostic trouble code (DTC) P0051 stands for “HO2S Heater Control Circuit Low (Bank 2 Sensor 1).” This code is logged when the powertrain control module (PCM) detects a potential issue with the heater circuit for the oxygen sensor #1 on Bank 2.
How does a mechanic diagnose the p0051 trouble code?
With the P0051 code, a car will still run and drive; in most cases, the illuminated Check Engine Light on the dashboard will be the only noticeable symptom. Poor fuel economy may be noticed, and the vehicle may run roughly. How does a mechanic diagnose the P0051 code?
Where is the O2 sensor on a p0051?
Specific repair steps may vary depending on the model. A P0051 DTC trouble code refers to the O2 sensor (oxygen sensor) located on Bank 2 in front of the catalytic converter. There is also an oxygen sensor behind the converter which is Sensor #2. Bank #2 is the side of the engine that does not contain cylinder #1.

Can a car scanner read both P0 and P1 codes?
There are certain types of faults in vehicles that will set a P0 code and not a P1 code or vice versa. Unless you’re able to read both codes it can be difficult for you to make the right diagnosis for your vehicle. Also, unlike code readers, scanners are capable of also displaying the readiness status of the car’s OBD2 system monitors.
Can a code reader turn off the Check Engine light?
With a code reader you can easily clear codes and turn off the “check engine” light, but you will however not be able to check for readiness and may fail to get a sticker in case your vehicle finds itself at the DMV’s office.
What causes a P0158 code?
The P0158 trouble code appears when the sensor has remained at a high voltage for too long. This oxygen sensor is located behind the catalytic converter. It sends information to the power control module (PCM) about the efficiency and released oxygen levels of the catalytic converter.
What does p0051 mean on the A / F sensor?
The sensor is less effective when the exhaust gas temperature is low, so it includes a heater which is activated to help get better readings from the A/F O2 sensor. Essentially this P0051 code means that the resistance of the heater circuit is lower than normal.
What does the p0051 code on a Toyota heater mean?
Essentially this P0051 Toyota code means that the resistance of the heater circuit is lower than normal. In most cases, that resistance level must fall below 0.8 A to trigger the DTC code.
How can I fix a p0051 DTC code?
To fix a P0051 DTC code, you’ll need to do a proper diagnosis. To do that, you’ll want to inspect the wiring and connectors leading to the sensor. Also if equipped with a heater relay and fuse, you’ll want to check those as well. Use a digital volt ohm meter to:
