P0037 is "Heater Control Circuit Low Bank 1 Sensor 2".

It sounds like it's time to check the connector to your oxygen sensor, and probably replace it (the O2 sensor).

Error Code: P0154
Description:
Heated Oxygen Sensor (HO2S) 1 , Bank 2 - No Activity Detected
Problem areas:
- Wiring.
- Open circuit in signal wire, between Heated Oxygen sensor 1, Bank 2 and ECM. (Must check and confirm)
- Heated oxygen sensor (HO2S).
- Engine control module (ECM).

Please provide the actual code for help with diagnosis.

Any unsolve wrong and the ECU is advise to you. Or forgetted RESET the error codes stored in the ECU.

Unplugged the negative battery few minutes, this operation reset your ECU; if this dont work, visit any auzotone or dealer shope foe reset your OBD codes.

you may have to have your catalytic converter replaced. isn't sensor 2 just before the? Just a thought. Leave a comment.

YOU NEED A DIAGNOSTIC SCANNER THAT WILL SHOW YOU TPS SENSOR OPERATION.WITH THROTTLE CLOSE TPS SENSOR VOLTAGE OUT PUT 0 AS YOU MOVE THROTTLE OPEN THE TPS SENSOR VOLTAGE SHOULD INCREASE TO 5.0 VOLTS THATS WIDE OPEN THROTTLE.
