Oxygen Sensor – Low Voltage?

December 22nd, 2010 · No Comments

I ran numerous Diagnostics tests with the OBD-II readers and replaced many oxygen sensors (Bosch and Delphi) with my 2000 Chevrolet Silverado. But my check engine light has been on for the past month with the new oxygen sensor. The last test, I replaced the Bosch oxygen sensor with a Delphi. I made a quick run to Tuffy and asked to run a test for my truck. They did. After that, it read O2 Sensor – Bank 2 Sensor 2 – Low Voltage. I know it’s downstream (passenger side, after the cats). The mechanic told me it has something to do with the wiring harness that connects to the computer, or a wire has been tugged/pinched during installation (made sure I didn’t touch anything other than the oxygen sensor).

December 19th, 2010 · No Comments

i was about to put a new pioneer radio in my car when i took the dash out and the stock radio instead of there being the one plug for the wire harness there was an addition black one…i dont know what the additional harness is for….can anyone help me with this?
is there a special harness i have to buy to plug in both cables or is there a way to work around it….without plugging in both of them the radio does not work.
- not sure for your exact car, a friend of mine has a 04 grand prix i think it is, had to buy some special harness to place the stock head unit in the trunk. the computer for the car is ran thru the head unit so it had to be there.. so it got stuffed in the trunk. they made a kid specially for it, i dont have links or anything but if it was that was for his it could be that way for yours, look into it and good luck

1995-1999 Ford Contour Radio Installation

August 4th, 2010 · No Comments

STEP 1: The Ford radio is snapped into the vehicles dash. With the proper tool, known as Ford radio removal keys, the Ford radio can be pulled forward out of the dash. A clothes hanger can be used instead of actual Ford radio removal keys. Cut the clothes hanger and bend 2 pieces in a ‘U’ shape. For more information on how to remove the radio, see the diagram below.
STEP 2: Pull the radio from the dash. Unplug the antenna cable from the rear of the radio. Unplug the 2 wire harness connectors from the rear of the radio. (This vehicle may have a Ford amplifier in the vehicle. This is the step you will be able to tell.)
Removing Ford Radios Using “U” Shaped Removal Keys
Insert the “U” shaped keys into the holes as shown in the diagram. Coat hangers can be cut and bent into shape for a quick, cheap replacement or alternative when Ford keys are not available. In order for the radio to be removed, clips attached to the side of the radio must be moved inward so the radio can slide out of the dash. Insert the keys and push each key out, away from the radio. The ends of the keys will press into the clips. While pushing the keys outward, pull and the radio should slide forward out of the dash.
Wiring The New Radio
Move to: Wire New Radio Section Your Ford may have the Ford Premium Sound System installed in it from the factory. This means the speakers in the vehicle are actually powered by a hidden Ford amplifier instead of the amplifier inside the radio (the amp is located away from the radios dash location). The “Wire New Radio” section will detail wiring for both the standard Ford radio and the wiring for Premium Sound System radio. The only way to tell the difference between a standard Ford radio and the Ford Premium Sound System is to pull the radio and look at the wire harness connectors plugged into the rear of the Ford factory radio. You will be able to see the 2 different sets of wire harnesses in the “Wire New Radio” section.
