SOURCE: dtc codes p0155 & p0051

I had the same problem and found out I was sold the wrong sensor, my 4.0 has four, they are all different, when you install a new sensor, you must make sure you clear the trouble code before you start the engine, ignition on engine off, that should do it, it worked for me, also if you have your own scanner and can erase the codes yourself, the wrong 02 sensor will turn engine light on with cold start, then after I erased the code it would stay off all day until the next cold start, thats when I found out my new 02 sensor was for bank 1 sensor 2, and not bank 2 sensor 1, hope this helps

P0155 error code Mitsubishi diamante 2002 where is it located the sensor


P0155 is not telling you which part is defective, it is saying there is a problem in the system and that the triggers the fault code. In this case you have a O2 sensor whose heater is not heating. This may be the senor or the wiring to it.
P0155 OBD-II Trouble Code: 02 Sensor Heater Circuit Malfunction in cylinder Bank 2 (V6 only), Sensor 1, this is the sensor before the catalyst.

Error code p0155 on ford windstar 2002


Hi there:DTC P0155 - 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)
This code refers to the front oxygen sensor on Bank 2. The heated circuit in the oxygen sensor decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0155.
A code P0155 may mean that one or more of the following has happened:

  • O2 Heater element resistance is high
  • Internal short or open in the heater element
  • O2 heater circuit wiring high resistance
  • open or short to ground in the wiring harness

Possible Solutions
  • Repair short or open or high resistance in wiring harness or harness connectors
  • Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)

I HAVE A1996 FORD EXPLORER WITH CODES PO133:02,PO155:02P1115


DTC P0133 - Oxygen Sensor Circuit Slow Response (Bank1, Sensor1)
This involves the front oxygen sensor on Bank 1. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use. You will likely not notice any drivability problems, although there may be symptoms.

A code P0133 may mean that one or more of the following has happened:
The oxygen sensor is faulty
The wiring to the sensor is broken / frayed
There is an exhaust leak


DTC P0155 - 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)
This code refers to the front oxygen sensor on Bank 2. The heated circuit in the oxygen sensor decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0155. See also: P0135 (Bank 1). You will likely notice poor fuel economy the illumination of the MIL.

A code P0155 may mean that one or more of the following has happened:
O2 Heater element resistance is high
Internal short or open in the heater element
O2 heater circuit wiring high resistance
open or short to ground in the wiring harness


DTC P0306 - Cylinder #6 Misfire Detected
A P0306 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #6. Symptoms may include the engine may be harder to start, the engine may stumble / stumble, and/or hesitate or other symptoms may also be present.

A code P0306 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer

My check engine light just came on. The diagnostics say that I need a P0155 sensor. I have a 2003 Toyota Highlander with a 3.0 engine.


P0155 indicates the heated O2 sensor is malfunctioning-If your oxygen sensor has 4 wires on it, it only means it has a heater circuit on it and it is used by the sensor to make the sensor more responsive to the demands of the engine. The heater usually is a separate circuit of wires that are use to supply power and ground to the heater element inside the sensor. To fix this code is normally done by replacing the sensor if they are more than 50,000 miles old (for older engines) and 100,000 miles for newer engines. If the signal wire does not switch, check the continuity of the signal wire from the sensor to your computer.

The only codes on your car that are only Ford codes are the one ranging in the 1000,s your codes start with 0,s there fore they are generic OBD2 codes
P0135=O2 Sensor Heater Circuit
P0155=O2 Sensor Heater Circuit
P0304=Cylinder 4 Misfire Detected
P0172=System Too Rich

My check engine lite is on in my 2002 sequoia. I went to get and auto inspection today and the truck failed. the tech said that it needed a p0155 02 sensor heater circuit. Can I replace the sensor myself?...


This code indicates a problem with the O2 sensor on bank #2. The sensor is located in the exhaust pipe close to the engine. It could be the sensor or the wiring to it.

For a good description visit
http://www.obd-codes.com/p0155

After the problem is fixed you should clear the code from the vehicle computer. Some auto parts stores will do this for free. After the problem is fixed the code will clear itself eventually but it will take several start ups.

Yes you can do it yourself if you are reasonably handy.

I have a 2004 Jeep Wrangler and the CEL came on so I went to Autozone and had it hooked up to a code reader and it came back with the code P0155. This has to do with the front oxygen sensor in Bank 2....


P0155 is an O2 sensor heater fault. Could be the wiring to the sensor, could be internal to the sensor. Good explanation here (I see you have been there too!)
http://www.obd-codes.com/p0155

Use a Volt/Ohm meter to check the wiring harness. If those check out okay then replace the sensor.

Replacing an O2 sensor doesn't take long if you can access it. Sometimes there's not much space to work.

As for the cold weather... the cold weather has probably just uncovered an issue with the heater that *might* go away when it warms up. However it will take a while for the CEL to go off.
