The 0037 is likely just a bad upstream O2 sensor bad, however their has been a Toyo service bulletin about this issue and for some models the sensor design has been changed such that the new part will no longer fit in the old exhaust manifold. This may be one for the dealer, sad to say.

Most likely the O 2 sensor is bad. You can check the harness. With key on there should be 2 positives sides and 2 negative sides.

Engine trouble codes


Hi CJ-
For many years now, engine codes have been standardized throughout the automotive industry to ease in vehicle diagnostics-so these codes are the same regardless of the maker of your car.
I use a site "engine-codes.com", to look these up on line. This is an excellent site since it not explains the code, but also troubleshooting methods for mechanics to fix the problem. For ease of information, I have provided the links for the codes you listed.
It sounds as though you may have issues with your O2 (oxygen sensor) which monitors the combustion and emissions system in your car.
Though rates vary from shop to shop, this should not be a wallet busting repair if replacement is needed.

your o2 sensor is bad. vsc will go on for any small DTC displayed on the MIL (cel)

P0037 LEXUS P0037 LEXUS - Oxygen Sensor Heater Control Circuit Low Bank 1 Sensor 2 Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
Possible causes - Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
- Faulty Engine Control Module (ECM) When is the code detected? The P0037 is set when the ECM detects an excessively low voltage through the heated oxygen sensor heater circuit P0037 LEXUS Description 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. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM).

In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECMcontrols the heater element circuit by allowing current flow to ground.

The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.
