What can cause a P0037 code?
What Causes the Code P0037?
- Faulty Bank 1 Oxygen Sensor 2 Heater (Most likely cause)
- Malfunctioning ECM Sensor Heater Driver.
- Shorted Control Circuit.
- A break in the wire between ECM and HO2S2.
- Poor Ground.
- Blown Fuse.
How is P0037 diagnosed?
P0037 is only diagnosed with an OBD-II scanner. The mechanic must reset the OBD-II code and test drive the vehicle to see if the code returns. If it comes back, the mechanic should check both power and ground to the sensor including inspecting the wiring and sensor.
What does Bank 1, sensor 2 on ho2s do?
The job of the HO2S is to read the oxygen content of the exhaust system and send that information to the PCM. The Bank 1, Sensor 2 refers to Bank 1’s second sensor on the back. The PCM will then use the information to monitor the catalytic converter’s efficiency.
What does Bank 1 sensor 2 stand for?
Bank 1, sensor 2 refers to the second sensor back on bank 1. The PCM uses the information gained from the Bank 1,2 HO2S mainly to monitor the efficiency of the catalytic converter. The PCM controls this heater to warm up the sensor to operating temperature.
What does the error code p0037 mean on an oxygen heater?
Error Code P0037 is defined as (HO2S) Heated Oxygen Sensor Heater Control Circuit Low, Bank 1 Sensor 2. This refers to a problem with the heater element circuit of the HO2S. It’s triggered when the PCM (powertrain control module, also called ECM or engine/electronic control module) detects an excessive low voltage through the HO2S.
What is the error code for ho2s heater?
Error Code P0037 is defined as (HO2S) Heated Oxygen Sensor Heater Control Circuit Low, Bank 1 Sensor 2. This refers to a problem with the heater element circuit of the HO2S.
What is the diagnostic code for ho2s Bank 1 sensor 2?
Cost of diagnosing the P0037 code. P0037 is a diagnostic trouble code (DTC) for “HO2S Heater Control Circuit Low (Bank 1, Sensor 2)”. 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 the ho2s code p0037 mean?
P0037 is the code for HO2S Heater Control Circuit Low (Bank 1, Sensor 2) What the P0037 code means. P0037 indicates that, for the engine to run correctly, the exhaust must have a specific air fuel ratio of 14.7 to 1 as determined by the Heated oxygen sensors (HO2S), which detects the oxygen content of the vehicle exhaust.
What is the code for ho2s heater control circuit low?
P0037 trouble code definition P0037 is the code for HO2S Heater Control Circuit Low (Bank 1, Sensor 2) What the P0037 code means P0037 indicates that, for the engine to run correctly, the exhaust must have a specific air fuel…
What causes a heater controller code of p0037?
Potential causes of a P0037 trouble code may include: Bank 1, sensor #2 oxygen sensor heater element has failed. Physical damage to heated oxygen sensor has occurred. Control circuit (or voltage feed, depending on system) is shorted to ground. PCM Oxygen sensor heater driver has failed.
How do I fix the code P0050?
What repairs can fix the P0050 code?
- Replacing the bank 2 sensor 1 (most common)
- Replacing the heater circuit fuse.
- Repairing any open or shorted wiring.
- Replacing the ECM (in rare cases)
How do you fix trouble code P0157?
What repairs can fix the P0157 code?
- Replacing the rear oxygen sensor.
- Repairing of broken circuitry or shorted wires going to the oxygen sensor.
- If the fuel pressure is abnormal, repairing the cause of the abnormality.
- Repairing the engine coolant temperature sensor if it is faulty.
What does bank 2 sensor 2 do?
Bank 2 is the set of cylinders that does not have number one cylinder. Sensor 1 is the sensor before the catalytic converter which the computer uses to make fuel ratio calculations. Sensor 2 is the sensor that comes after the catalytic converter and is mainly used for onboard emissions testing.
