    Who is SNG-02?

  • leooostra Jul 28, 2008

    Yes, your advise is a good one.

    The dealer sensor price was $321.00 (incredible)



    Your source (Oxygengeek) $41.00

    Thanks again, and keep up the good work

MR988905 costs $300+

SNG O2 sensor is just below $100

they may claim being made with the same quality and both are tagged "direct fit" for easy installation.

its just my idea, good luck.

Could the catalytic converter cause this code 2002 mitsubishi montero sport 3.5 p0161 code changed the o2 sensor and still get the same code could the catalytic converter cause this code


No it has nothing to do with the cat.
Code 161 is for a problem with the heater circuit for sensor 2 bank two. Either the heater in the sensor has failed, or the circuit that powers the heater is not working.

Has any one had problems with bosh oxagen sensor not working properly


Hi there:
Are you buy same or OE part replacement according with the Hyundai part number catalogue? This is important. Keep in midn that you need reset or delete all previous code stored in the car computer.


DTC P0131 - Oxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 1)
Essentially the same as P0136 and P0137, a P0131 code refers to the first oxygen sensor on Bank 1. P0131 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 1 is located in front of the catalytic converter.


There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination.


A code P0131 may mean that one or more of the following has happened:
- Faulty o2 oxygen sensor
- Short to voltage on O2 signal circuit
- High resistance or open on O2 signal circuit


Possible Solutions:
- Replace faulty sensor
- Repair short, open, or high resistance on o2 signal circuit


Now, about DTC P0135 - Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)


A code P0135 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)


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, have a nice day.

Error codes po 134 po 153 po 154 po 155 po 171 po 174


PO 134 = 02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 1 SENSOR1)
PO 153 =02 SENSOR CIRCUIT SLOW RESPONSE (BANK 2 SENSOR 1)
PO 154 =02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 2 SENSOR 1)
PO 155= 02 SENSOR HEATER CIRCUIT MALFUNCTION (BANK 2 SENSOR 1)
PO 171= SYSTEM TOO LEAN (BANK 1)
PO 174= SYSTEM TOO LEAN (BANK 2)
I WOULD SAY YOU HAVE FAULTY OXYGEN SENSORS CAUSING THE ENGINE TO RUN TOO LEAN REPLACE THEM AND YOU SHOULD BE BACK IN BUISNESS

I'm thinking about buying a 2002 range rover. It has a service/check engine codes of 134,135,155. Is it likely to be more than oxygen sensor problems? Please reply , Mel


with those codes showing, it could be either bad O2 sensors or there is a problem with the wiring to those sensors. Also, the wrong sensors may be installed. I'm assuming codes P0134, P0135, P0155.

For others viewing this:

P0134 = O2 sensor circuit-no activity detected (bank 1 sensor 1)

P0135 = O2 sensor heater circuit malfunction (bank 1 sensor 1)

P0155 = O2 sensor heater circuit malfunction (bank 2 sensor 1)
