P0050 CHEVROLET code

What the P0050 code means. This code is found when the Engine Control Module (ECM) has detected an issue with the heater control circuit for the bank 2, sensor 1 oxygen sensor. The heater circuit is used by the ECM to heat the oxygen sensor to proper operating temperature for an accurate reading.

What is a heater control circuit Bank 1?

What Does the P0030 Code Mean? Diagnostic Trouble Code (DTC) P0030 stands for “HO2S Heater Control Circuit (Bank 1, Sensor 1).” It may be triggered when your vehicle’s control module detects a fault in the heater circuit in oxygen sensor Bank 1, Sensor 1. Bank 1 is where cylinder number 1 is located.

What is a HO2S heater control circuit bank 1 sensor 2?

Diagnostic Trouble Code (DTC) P0037 stands for “Heated Oxygen Sensor (HO2S) Heater Control Circuit Low (Bank 1, Sensor 2).” It refers to a malfunction in the heating element of the downstream oxygen sensor behind the catalytic converter.

What is heater circuit bank 2 sensor 2?

This code means that the bank 2 sensor 2 oxygen sensor is not warming up properly due a problem in the oxygen sensor heater circuit. Vehicle emissions could be increased due to this problem.

How do you fix P0038?

In most cases, replacing the faulty oxygen sensor will eliminate the problem responsible for the P0038 code. The exact fix, however, will likely differ based on the make and/or model of the vehicle.

How do I fix the code P0050?

What repairs can fix the P0050 code?

  1. Replacing the bank 2 sensor 1 (most common)
  2. Replacing the heater circuit fuse.
  3. Repairing any open or shorted wiring.
  4. Replacing the ECM (in rare cases)


How do I fix my HO2S heater control circuit?

If the battery feed is correct, remove the ground (control) circuit from the ECM wiring connector and check for resistance on the circuit. If there is infinite resistance, repair the open in the circuit. If the control circuit is good, suspect a bad O2 sensor. Replace and re-check.

How do I fix error code P0060?

What repairs can fix the P0060 code? Usually a replacement of bank 2 oxygen sensor 2 will fix this particular code.

What is heated oxygen sensor?

OBD II equipped vehicles use heated oxygen sensors. Heated oxygen sensors have an internal heater circuit that brings the sensor up to operating temperature more quickly than an unheated sensor.

How does a catalytic converter sensor work?


Zitat von Youtube: Go through the honeycomb. And a catalyst substrate. And then they're turned into carbon dioxide water and nitrogen. That's how we take in air and fuel manage. The combustion process with an o2 sensor.

Where is the heater control circuit bank 2 sensor 2?

Bank 2 is the side of the engine that does not contain the #1 cylinder. The oxygen sensor 2 located on this bank is also known as the downstream oxygen sensor because it is located after the catalytic converter.

  C0040 CHEVROLET code

Which side is bank 2 sensor 2?

All oxygen sensors are located on the exhaust system, Bank 2 for your engine will be the bank of cylinders closest to the front of the car. Sensor 2 will be the second oxygen sensor downstream on that side of the exhaust pipes, after the catalytic converter.
