2001 Cadillac Deville oxygen sensor wiring diagram


The wiring diagram shows the wiring color code, Power rating and connector plug used. The wiring diagram explains the vehicle's electrical connections with color code. It's a bit complicated to understand.

My running lights in my toyota sienna 2007 stop working


Go to Autozone.com and register your vehicle for free. Then you can get free wiring diagrams and fusebox layouts to help trace the wire.

Once you see a power wire or ground wire which makes that string of lights work, you can fix it. The wiring diagrams are color identified to help.

My Toyota Sienna shows VSC light on the broad. What Should I do?


Hi there,

If you've had your vehicle computer codes read and determined no issue with the VSC circuit, then you just need to cancel the warning light.

I've made up the following instructions, on how to clear VSC & TRAC Warning lights:



Zero Point Calibration of Yaw Rate and Deceleration Sensors Using Paper Clips (or jumper wires).

First, locate the 16-pin ODB II connector under the steering wheel (beneath the dash). The pins are numbered sequentially backwards from right to left (from the wide side of the connector looking at it from underneath).


Take two normal-sized paper clips (or suitable jumper wires). If using paper clips, straighten one edge of one of the paper clips. For the other, bend it open to a 90-degree angle (like an elbow).


Insert one paper clip/wire into pin # 14 (Ts), and the other paper clip/wire into pin # 4 (CG) of the OBD II connector - DO NOT allow the paper clips/wires to make contact at this point.
Refer to diagram below:

1. Ensure the shift lever is in "P" range.


2. Turn the ignition switch to "ON" (not start).


3. Momentarily touch the two paper clips/wires together (short) and separate again (open) - Repeat this process 5 times (within 8 seconds of turning ignition on).

Verify that the VSC indicator light is illuminated, indicating the Recorded Zero point is erased.


4. Turn the ignition switch "OFF".


5. Remove both paper clips/jumper wires from the OBD II connector.


6. Turn the ignition switch "ON" (not start) - wait until VSC warning light turns off (approx. 20 seconds), then wait 2 seconds.


7. Turn the ignition switch "OFF".


9. Re-insert paper clips/jumper wires to terminals #4 & #14 of the OBD II connector (as per above diagram).


10. Turn the ignition switch "ON" (not start) - VSC warning light should remain illuminated for 4 seconds, then start flashing at 0.13 second intervals.


12. After VSC warning light flashes for 2 seconds, turn the ignition switch "OFF".


13. Remove paper clips/jumper wires from the OBD II connector.



Drive your vehicle to confirm VSC & TRAC warning lights have been reset and no longer illuminate.

Toyota Sienna 2000 Mini-van. The driver's side power window.


I have the same problem with my 2000 Sienna.Probably window motor will need replacement. Frustrating. Turns out I have a lot of the same wear and tear issues with my Sienna as others. Automatic door sticks open or continually pops open, snapped rear hatch, tire pressure sensor always on. C'mon Toyota, I hope your newer models are more robust. FYI we take VERY good care of our van.

Which O2 sensor for 2005 Dodge Ram Quad 5.7 (Hemi); the parts stores asked if I needed the 2,3 or 4 wire. My Vin starts with 1D7HA18DXXXXXXXXX


Which O2 sensor do you need, you have 4 O2 sensors in your Dodge ram. Is it the O2 sensor upstream or the down stream. I believe the down stream will have the 4 wire lead and the up stream will have the 3 wire leads. If you need the down stream O2 sensor which is the common one to go bad, you can look at the wire harness clip which is only 6 inches a way form the sensor after the catalytic converter. Good luck and hope this helps.
