|
|
What are you folks doing when it comes time to replacing the O2 sensor? My parts guy will sell me the replacment O2 that has the correct wiring plug for $47.00, or I can get the Bosh one for under $10.00, which would only require me to cut and splice it on.
Acceptable to splice a single wire Bosh and save $37.00, or is there something "special" in using one with the wired plug end? |

I did. I soldered it too after crimping it. The generic Bosch single wire sensor comes with a ferrule just for that. Then used a piece of small heatshrink tube over the connection. I also slipped another tube over the wire to protect it more. Don't forget the grommet in the engine tin where it passes through.
I used a Bosch one with the following numbers on the box:
11027
0258001027009
489992
UPC code 0 28851 14027 0
Premium Oxygen Sensor

So once it has been replaced, how do I reset the warning lamp on my dash? |

Ditto on the universal sensor. The reset button is on the speedo on the front drivers side wheel if I'm not mistaken. _________________ 84 Westy 4spd sold |

Trace the speedo cable from the wheel, along the way you will find a junction box that it runs into. This box has a reset button. The O2 sensor light is not a fault light, the box tracks mileage and sets it off on a set schedule. Push the button and viola light is off. |

Has anyone had any problems with the cheap $40 dollar general Bosch O2 sensor since it was installed?
Any inspection passing issues?
Thanks,

This is what I LOVE about this forum. My O2 Sensor light comes on... and I go okay.. now what??
A two minute research job here tells me about the whole reset thing. I find the box. Driver side front of the wheel mounted to the frame. I find the button. Oh by the way, a small phillips head screwdriver works great because you have to push it All the way in.
Light is off. Problem solved for the time being.

Make sure you get the three wire O2 sensor not the one wire. Heated O2 sensors are a wonderful thing and your van will thank you.

A heated sensor is indeed better, but only 86+ have the heater power supply circuit, earlier vans just use the one-wire sensor. Wouldn't be at all hard to add a heater circuit, though, probably worthwhile especially for urban drivers and for passing the idle emissions test. _________________ Shop for unique Vanagon accessories at the Vanistan shop:

So my FLAP'S Universal 02 sensor has 3 wires; a Grey, Black, and a White. Do I splice the green shielded wire into one specific wire or do I just link them all ?
-Thanks |

One is signal (likely grey) , another is ground (black) and last is 12v (white). Your ECU signal wire must only be connected to the o2 sensor signal. To do otherwise will result in a very poor running van. _________________ Cheers,

Okay, grey wire (signal) to the green wire (to ECU). Should I ground the new sensor or just cut the ground back? |

It's already grounded via the exhaust. The white and black should just be capped. You could run 12v to the sensor heater wires to speed the system closed loop cycle...otherwise insulate and secure those wires. _________________ Cheers,

The location of this black box is so unexpected. With road grime it is also hard to see the button. Here is a picture of the box…
