the coolant temp sensor is at the rear of the engine and is a "bad word" to get to. the 3 relays are at the bottom,under the fans. if you remove the driver side fan out of the way( 2 10mm bolts holding the fan) you should have good access to them. they do have locks on them and may be tricky to unplug. there is a 7/16 nut holding the relay plate down. remove and it should be easy to remove them.

Since replacing anything could cost hundreds of dollors, would you really replace it from a suggestion or would you prefer to get it diagnosed properly. It gets expensive when you just throw parts at a car. This really need to be diagnosed properly ( hands on with the proper equipment).

'95 Lincoln town car. Husband was driving uphill and the digital dash suddenly went dark. Radio is working and a/c is not. Exterior light still working and so are interior lights besides the dash


Could be a bad wire possibly chaffing or grounding out to to another wire or frame. Check your fuses. You may want to pull the dash out and check that wiring as well

1992 toyota 4runner sr5 speedometer stopped working and check engine light illuminates


If you have someone check the engine computer for trouble codes, you'll probably find a code for the speed sensor in the transmission.

Transmission speed sensor


You could have a faulty speedometer/odometer combination meter causing a false Vehicle Speed Sensor error.
My 1998 Sienna had the following symptoms:
- Speedometer and odometer failed intermittently
- The check engine light would come on and I would get a p0500 code in the OBDII.
- The cruise control would stop working at the same time the speedometer failed.
There is a speed sensor in each one of the tires and they feed the speed information to the ABS ECU. From the ABS ECU the speed signal goes to the speedometer/odometer combination meter, and from there it goes to the Engine Control Module and to the Cruise Control ECU. I could see a signal coming into the speedometer/odometer, but no signal going out. Replacing the speedometer/odometer combination meter fixed the problem.

Check engine light on, Brake and ABS lights illuminate, speedometer fails and odometer goes to dashes. The problem is intermittent but happening daily, turning the car off and then back on seems to reset...


to make sure, you would have to have the vehicle scanned with Volvos' Vida scanner. However, the most common problem is usually the control unit.

Car speedo & odometer sometimes work OK, other times not at all.


Most likely a speed sensor is going bad (most cars and truck do not use mechanical speedometer cables anymore) most sensors are located near the differential in rwd cars or near the drive shaft on the transmission. Best bet is to get a Haynes manual for your car to help locate the speed sensor. Remove it and take it to the auto parts store so you can visually compare it to the replacement. Install the new speed sensor and it should restore your speedometer and odometer.

99 jetta check engine light on, runs fine, speedometer not workin


o2 sensors will put your check-engine-light on. it is attached to the exhaust (closest to the motor)and rusts-out sometimes. you could try to fix it by buying the o2 sensor and use a socket-set to see if it loosens. i 'm not a mechanic but have had the issue, in the past, with the jetta II's and a 1997.the guys at vw dealers are great with info, if your a hands-on kinda guy/girl.

It may be a faulty speedometer with a short inside, or a short on speedometer wirings or connector.

Whenever car vibration cause the wiring to short, there you lose speedometer and trans functionality.

You need to access the speedometer connector and wirings to
instrument panel to fix this.
