Question about 2000 Chevrolet Malibu

1 Answer

99 Malibu all of a sudden my speedometer started bouncing wildly

Drove the car to work, half way there cruise control disengages and the car slows, give it gas and it speeded up, but then speedometer starts bouncing like a stero output signal or something. Stayed thet way till I got to work. Started home, speedo starts flippening out again after 14 minutes into trip home. Anyone Know whats going on and is it hard to fix?

I'm not 100% sure but your problem may be a speed sensor.  This is just a sensor that monitors how fast the tires are moving.  These are usually easy to change.  They require usually one or two bolts to be removed and an electrical plug.  But as to the location of yours, I'm not 100% sure, but I believe it mounts somewhere on the transmission (transaxle.)
Any questions, just ask!!! Please rate!!!  Thanks

What does the MIL code "PO 320" mean, please?


code p0320 refers to cam shaft position (CKP) sensor/engine speed (RPM) sensor--circuit malfunction=== causes --wiring--CKP/RPM sensor ---ECM
because the engine runs ok until it is on cruise control I would be investigating the RPM sensor for a fault
The cruise control takes its control from the RPM sensor and if that circuit is interminable the the cruise control doesn't know what rpms to maintain.

93 toyota pickup 5 speed, speedometer and odometer work intermit


There is a plastic helical gear in the transmission, where the speedometer cable attaches. Start there. Usually 2-3 bolts that hold it in, when it comes out, some fluid will escape. Check that gear for wear, and broken splines. Then follow the cable up to the cruise control module. Some cars route the speedometer cable to the cruise control transducer, then to the firewall to the instrument cluster. That transducer goes bad. Thats what happened on my 81 olds. The speedometer would bounce around at speeds less than 15 mph. I replaced that transducer and it is steady now.

My speedometer bounces when i hit 45 miles an hour, what do i need to do?


Hi.

Problem is usually the speed sender failing when speed gets too high. In some case the speed gauge itself is damaged. In Mercury the speed sender is located in the transmission. The part is difficult to test without professional equipment. Repair is done replacing the speed sender. If that does not fix the problem, work on the instrument panel speedo.

Here location of the speed sender:

'99 Beetle cruise control surge and speedometer has slight flutter.Occasionally speedometer drops to zero mph and cruise will then stop working. The "surge" is so bad that you can not drive with cruise on....


I would take a blind guess and sat the speedo sensor has an issue. 99' beetle should have an 01M auto, and the speed sensor is also the dipstick for the final differental drive. search around this area of the trans for the cable and snoop around. loose at the trans ? bad connection somewhere??
