H.e.g.o sencer


A HEGO sensor is a voltage generator that is in the exhaust system installed between the manifold and the catalytic converter. It is used to sense the amount of oxygen present in the exhaust gases. Two wire type, black wire is earth, grey wire is sensor signal. If four wire type black is earth, grey sensor signal, two white wires are for a heater circuit.

01 vw Jetta trubo 2.0 code p1113



Trouble Code: P1113

O2 Control (Bank 1 Sensor 1) Internal Resistance Too High
Possible Causes:


Oxygen sensor (before catalytic converter) is faulty. Oxygen sensor (behind catalytic converter) is faulty. Oxygen sensor heater (before catalytic converter) is faulty. Oxygen sensor heater (behind catalytic converter) is faulty. Circuit wiring has a short to power or ground. Engine Component Power Supply Relay is faulty . E-box fuses for oxygen sensor are faulty . Leaks present in the exhaust manifold or exhaust pipes. HO2S signal wire and ground wire crossed in connector . HO2S element is fuel contaminated or has failed. ECM has failed .Here is what is listed.

1996 GRAND CHEROKEE CODE #P0141 AND P0138


Hi there:
Both codes refer at O2 sensor...


DTC P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)
This code means that the heated circuit in the oxygen sensor on bank 1 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 P0141. See also: P0135 (Bank 1, Sensor 1).



You will likely notice poor fuel economy the illumination of the Check Engine Light.



A code P0141 may mean that one or more of the following has happened:
open or short to ground in the wiring harness
O2 heater circuit wiring high resistance
O2 heater element resistance is high
Internal short or open in the heater element
Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.


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





DTC P0138 - O2 Oxygen Sensor Circuit High Voltage (Bank1, Sensor2)
The Heated Oxygen Sensor (2) located rear of catalytic converter produces an output signal relative to oxygen storage capacity of catalytic converter. Ho2S 2 signal is less active than signal produced by front oxygen sensor. This code sets when HO2 Sensor voltage is greater than 999 mV for more than 2 minutes (time depends on model. Could be as high as 4 minutes)



There may be no noticeable symptoms except for MIL illumination. Possible high fuel pressure can over rich the system.


A code P0138 may mean that one or more of the following has happened:
Faulty O2 sensor
Short to battery voltage in O2 sensor signal circuit
High fuel pressure (not as likely)


Here are some potential solutions:
Replace O2 sensor
Repair short to battery voltage in o2 sensor signal circuit.


Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

What are the color codes for a 1996 jeep grand cherokee 6 cyl oxygen sensor. The connectors are missing and I am putting in a new sensor with 2 white 1 black and 1 grey wires


Well the 2 wires that are same color are the heater wires, and then for the other 2 colors, you will have to consult the manual that comes with the universal oxygen sensor. One will be a 5 volt constant from the computer, and the other will be the signal return. So you know which wires are what on the truck, I have the diagrams right here:

thanks for asking.

When you bought the replacement sensor it should have included instructions on what color wires match. If possible I would return to the store you bought it from and ask for the included directions.

The blacks go together and the greys go together, but I am not sure which other ones go together without knowing the brand and P/N of the replacement sensor.
