There is four wires-two of them is white for the heater and another two is grey and black for the sensor.Zirconia or titania doesn.t matter.

0152 coed


P0152 P0152 - O2 Sensor Circuit High Voltage Bank 2 Sensor 1Possible causes - Faulty Front Heated Oxygen Sensor Bank 2
- Intake air leaks may be faulty
- Exhaust gas leaks
- Front Heated Oxygen Sensor Bank 2 harness is open or shorted
- Front Heated Oxygen Sensor Bank 2 circuit poor electrical connection
- Inappropriate fuel pressure
- Faulty fuel injectors
eplacing the Front Heated Oxygen Sensor Bank 2 usually takes care of the problem
Symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- High Fuel Consumption
- Excessive Smoke from Exhaust P0152 Description The front heated oxygen sensor (or O2 sensor 1) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas compared to the outside air. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The heated oxygen sensor 1 signal is sent to the Engine Control Module (ECM). The ECM adjusts the injection pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical change from 1V to 0V.

Code 16518 on mk4 golf


Can't by pass as oxygen sensors control your fuel

I suspect your exhaust converter has failed & the car has
been running rich for years & ruined it

Wouldn't your repair guy be able to solve all your issues,
after all you were at a shop for some work

Sounds like they sold some service instead of diagnosing
the reason you were there

Where is the oxygen sensor on the car golf 4 gti 1.8t


You have one before the catalytic converter and one after. They look similar to a short spark plug with a single wire protruding from the end, and are threaded directly into the exhaust pipe.

Colors of wires of MAF sensor in 2001 VW golf gti vr6


2001 VW Golf GTi VR6
On the MAF sensor connecting plug you will see 5 pin numbers. Each pin number correspond to a wire color:
Pin no.# 1 = violet/green, is comming from pin no.# 26 of ECM. ECM = Engine Control Module.
Pin no.# 2 = blue/yellow, is comming from fuse no.# 43 = 10 Amp. (battery plus is comming through a blue wire from pin no.# 23 of fuel pump relay).
Pin no.# 3 = green, is comming from pin no.# 27 of ECM.
Pin no.# 4 = red/violet, is comming from pin no.# 53 of ECM.
Pin no.# 5 = black, is comming from pin no.# 29 of ECM.

Check Engine light with Po131 o2 circuit low voltage sensor 1 bank 1 reading, what does that mean?


- Front Heated Oxygen Sensor Bank 1 harness is open or shorted
- Front Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Front Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks

Replacing the O2 Sensor 1 usually takes care of the problem

The front heated oxygen sensor (or O2 sensor 1) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas compared to the outside air. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The heated oxygen sensor 1 signal is sent to the Engine Control Module (ECM). The ECM adjusts the injection pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical change from 1V to 0V.

98 jeep grandcherokee code PO138, PO141 & PO463


P0138 - O2 Sensor Circuit High Voltage Bank 1 Sensor 2

The rear heated oxygen sensor (or sensor 2), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank. Even if switching characteristics of the heated oxygen sensor 1 are shifted, the air-fuel ratio is controlled to stoichiometric, by the signal from the heated oxygen sensor 2. This sensor is made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. Under normal conditions the heated oxygen sensor 2 is not used for engine control operation.

Causes:
- Harness or connectors (The sensor circuit is open or shorted)
- Rear heated oxygen sensor (Bank 1) may be faulty

Solutions:
Replacing the O2 Sensor 2 usually takes care of the problem


P0141 - O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 2

Causes:
- Harness or connectors (The sensor circuit is open or shorted)
- Rear heated oxygen sensor (Bank 1) may be faulty

Solutions:
Replacing the O2 Sensor 2 usually takes care of the problem


P0463 - Fuel Level Sensor Circuit High Input

The fuel level sensor is mounted in the fuel level sensor unit. The sensor detects a fuel level in the fuel tank and transmits a signal to the ECM or PCM, It consists of two parts, one is mechanical float and the other side is variable resistor. Fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.

Causes:
- Fuel level sensor circuit harness or connectors is open or shorted
- Fuel level sensor may be faulty

Solutions:
Replaced fuel level sensor.

2001 silverado po300 code and po135 code changed 2 o2 sensors still coming up have not changed driver side o2s yet


Well the P0300 code has nothing to do with your O2 sensors just a heads up.

P0300: Random/Multiple Cylinder Misfire Detected

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the crankshaft position (CKP) sensor (POS) signal to vary, Powertrain Control Module (PCM) or Electronic Control Module (ECM) can determine that a misfire is occurring.

Causes:
- Improper spark plug
- Insufficient compression
- Incorrect fuel pressure
- The injector circuit is open or shorted
- Fuel injectors may be faulty
- Intake air leak
- The ignition signal circuit is open or shorted

Solutions:
- Perform Injector Service
- Replace Spark Plugs
- Replace Injectors
- Replace Ignition Coils

P0135: O2 Sensor Heated Circuit Malfunction Bank 1 Sensor 1

The front heated oxygen sensor (or sensor 1) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas compared to the outside air. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The heated oxygen sensor 1 signal is sent to the ECM. The ECM adjusts the injection pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical change from 1V to 0V.

Causes:
- Harness or connectors (The sensor circuit is open or shorted)
- Front Heated oxygen sensor (Bank 1) may be faulty

Solutions:
Replacing the O2 Sensor 1 usually takes care of the problem

When is the code detected? - Current amperage in the front heated oxygen sensor heater circuit is out of the normal range. (An improper voltage drop signal is sent to ECM through the front heated oxygen sensor heat a four thumbs up would be helpful if this fixed your problem thanks have a nice day
