P0135 O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 1 P0141 O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 2 P0155 O2 Sensor Heater Circuit Malfunction Bank 2 Sensor 1 P0161 O2 Sensor Heater Circuit Malfunction Bank 2 Sensor 2 Seems to me that all of my O2 sensors wouldn't go bad at the same time, so I'm thinking it is something else. Heated oxygen sensor - Bank 2 Sensor 1 (H02S21) Sensor circuit no activity detected Explanation: Air/Fuel ratio concern - lean or rich Probable cause 1. The heated oxygen sensor senses the oxygen concentration in the exhaust gas and, converts it into a voltage which is sent to the ECM. O2 Oxygen Sensor Heater Circuit Malfunction (bank 2 sensor 1) What the P0155 code means. That said, the code you have is for the heater circuit. The codes are P0030 and P0135, which both point to O2 sensor, bank 1 sensor 1. The Check Engine lamp came on. Post Reply. What does trouble code P0141 O2 sensor heater circuit malfunction bank 1 sensor on a 1996 chevy corsica mean? it means that your O2 sensor has to get replaced. Does anyone know where this particular sensor is because I understand there are FOUR? I have a 2001 SR 2. Look at the exhaust manifold nearest the firewall (dash). P0032 - Oxygen (A/F) Sensor Heater Control Circuit High (Bank 1 Sensor 1) P0029 Exhaust Valve Control Solenoid Circuit Range/Performance Bank 2; P0026 Intake Valve Control Solenoid Circuit Range/Performance Bank 1; P001A A Camshaft Profile Control Circuit/Open Bank 1; P0012 - "A" Camshaft Position - Timing Over-Retarded (Bank 1). As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. CEL came on while driving this afternoon. The heated circuit in the oxygen sensor decreases time needed to enter closed loop. Sensor 1 is the upper sensor or upstream sensor in the manifold, Sensor 2 is the downstream sensor. This O2 sensor #1 may also be refered to as an air/fuel ratio sensor.

A typical in-line 4-cylinder engine has only one bank (Bank 1). An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analysed. My question is about a fuse for these sensor heaters? I've done a bit of research on the web and suspect it's something common like a fuse but I can't find any reference to where this could be.
