What does the p0051 code on a car mean?
What the P0051 code means. This code is set when the car’s computer, or Engine Control Module (ECM), detects low system voltage in the heater control circuit. Specifically, the code is referencing Bank 2 Sensor 1.
Where is the O2 sensor on Nissan p0031?
A P0031 Nissan DTC (diagnostic trouble code) definition:the O2 sensor (oxygen sensor) located on Bank 1 in front of the catalytic converter. There is also an oxygen sensor behind the converter which is Sensor #2. This O2 sensor #1 may also be refered to as an air/fuel ratio sensor since on some vehicles it is.
What does the p0031 code on a Nissan heater mean?
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 P0031 Nissan code means that the resistance of the heater circuit is lower than normal.
What is the diagnostic code for ho2s Bank 2 sensor 1?
Cost of diagnosing the P0051 code. P0051 is a diagnostic trouble code (DTC) for “HO2S Heater Control Circuit Low (Bank 2 Sensor 1)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What does p0051 mean on Bank 2 ho2s1?
What Does P0051 Mean? The P0051 code is a result of the bank 2 HO2S1 (pre catalytic converter heated oxygen sensor) heating element having low voltage. Heated O2 sensors have a separate heater inside the sensor to get them to operating temperature quickly.
Can a faulty oxygen sensor cause a p0051 code?
Code P0051 can be triggered by anything from a defective oxygen sensor to a faulty PCM, so you must do your research thoroughly before attempting to resolve this code. It’s best to leave repairs to the experts if you aren’t confident in your automotive repair skills.
Why does the ho2s heater control circuit log p0051?
This is why it contains a heater wire which can bring its temperature up quickly when needed. When the PCM detects that the resistance of the heater circuit is lower than normal, it logs P0051. The oxygen sensor measures the amount of oxygen present in the exhaust gas and compares it to the air outside.
What does the DTC code p0051 stand for?
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.
