This is front o2 sensor that is probably taking too long to heat up try a fuel additive that works on the catalytic converter as well as engine may just be a carbon build up if still causing a problem after thet renew sensor

SOURCE: check engine light on code is P0155-02

I had to replace both o2 sensors on my 2002 Tundra after about 50K. Toyota recalled this problem afterwards and refunded my money. My solution to you is to not worry about which one is bad and go ahead and replace both, because I had one bad and before I could replace it the other went bad also. PS: You'll have to purchase a special socket to remove them and unless you pruchase the Toyota product ( I used O'Reilly parts), you have to cut and splice the wires with a waterproof splicing kit included with the sensors. Just follow the instructions, not a hard job.

SOURCE: Error P0155

That code will not affect the drivability of the vehicle. The heater does just that: it heats up the oxygen sensor to operating temperature. You can change it yourself, raise the vehicle up, the sensor is the one on the passenger side, right after the exhaust manifold.

Thanks for choosing FixYa for advice!

SOURCE: Check engine error code P0155

If you used the type you splice the wires, recheck the wires. Sensor 1 should have been the one up closest to the exhaust manifold. I prefer to pay $30 more and get the OEM plug-in type. You might try disconnecting the battery for a while.

In that particular engine the sensor that you have is the one in the driver side, but based in my experience you have to replace both, the same in tundras, the computer sees a fresh new, fast signal, from the new sensor and thinks that the sensor and the opposite bank fail.

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.

Jeep grand cherokee p0155 code p1494


For the P0155 code, check the fuse for the O2 heater circuit.
The P1494 has to do with the EVAP leak detection pump pressure switch. Or the switch is faulty, or there is a large leak. Do you hear any hissing sounds under the jeep?

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)
