What should I do if my p0037 code returns?
If the P0037 code returns, then follow the test procedure. It can have several problems, but wiring being damaged by excessive heat from the exhaust is most common. Make certain the wiring is good and has proper voltage and ground to the sensor before replacing the sensor.
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 happens when you change the O2 sensor?
The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle’s computer. The ECU then adjusts the air-to-fuel ratio to optimize the fuel combustion. Sometimes an O2 sensor fails, and you need to replace it.
Why is the OBD-II code not coming back?
If the code is cleared and reset, and then the Check Engine Light and the OBD-II code comes back, the HO2S sensor for the engine bank 1 and sensor #2, which is to the rear of the catalytic converter, is not sending the correct information to the ECM and may be damaged or defective.
What does the p0037 code on the oxygen sensor mean?
The P0037 code is set when the ECM detects that the HO2S2 on bank 1 has a malfunctioning heater element. The heater in the oxygen sensor helps get the sensor up to operating temperature faster in order to improve fuel economy and emissions.
When is the p0037 Toyota code detected?
When is the P0037 TOYOTA code detected? Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal.
What to do if your engine light says p0037?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals. The cost of diagnosing the P0037 TOYOTA code is 1.0 hour of labor.
What does DTC p0037 mean on a ho2s heater?
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. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
