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)

2001 Toyota Sequoia Oxygen sensors


No the wires won't likely be the same length

The front upstream sensors, are not the same
Part # as the rear,downstream monitor sensors

Go to Rock Auto.Com & look up your oxygen sensors
I would get the NTK or Bosch,if they have that

You do not replace the rear sensors, until they fail

You replace the front ones at 100,000 miles or sooner,
if they fail

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


DTC P1115 - Intake Air Temperature 2 Circuit High Input (Super/Turbo Charged engines)


In the next diagram could checl this specific location about each O2 sensor...

I HAVE THIS CODE IN MY IZUZU RODEO 2003: P0155


this code is oxygen sensor heater circuit range/performance(bank2,sensor1)
the ECM detects the heated oxygen sensor internal resistance is not in specs for 6 seconds code sets
disconnect O2 sensor,switch ignition on engine not running and measure the voltage with a multi meter between O2 sensor reference signal circuit and low reference signal circiut(vehicle side of wiring) should read 350-550mV
possibly O2 sensor broken(faulty) replace

P0155=O2 Sensor Heater Circuit
P0304=Cylinder 4 Misfire Detected
P0172=System Too Rich

P0155?


P0155 OBDII code refers to HO2S heater circuit - bank 2 sensor 1 , not knowing your engine size and engine vin code thats about as far as we can go with our answer . we can say bank 2 sensor 1 is the passenger side upstream oxygen sensor has a heater circuit problem , could possibly be a bad oxygen sensor . you ask what is that - thats what it is ... cheers .
