1997 isuzu rodeo speedometer/odometer quit working, check engine light on

Just turned 89k and speedometer/odometer quit working, about 3 miles later the check engine light came on. I can afford parts, but cant afford a mechanic to "diagnose" it. I have heard it could be a sensor, but when I look there are 2.....pricey to get both, but is the my best bet?

I suspect that the TCM is playing up but without a proper code reading it is difficult to say. Why do you not take it to autozone as they do scanning for nothing.

    Thanks guys! I did run to Autozone on my lunch today and it threw a P0502. They said it is the speed sensor. Found it is cheaper to get it online then through anyone local. Will get it in when it comes and HOPE it is the issue!

Hi Jack,

I am not an expert and I don't have the codes in front of me with the meaning but I can offer some advice and hopefully it will solve your problem. First keep the print out of the codes and take it/them with you. Have someone check the oxygen sensor. It's possible that all of the codes you are getting lead up to the computer (electrical issue). I sure hope this helps. Good luck and let me know how things turn out.

after you did that did you hook it to a car computer to reset the lite? most need this and you can go to a auto zone and rent the computer for free just a deposit and then you get that back. the computer will do it almost for you.

SOURCE: 2000 Isuzu Rodeo speedometer and odometer notworking. fuel light flashing with gas in it

Go to Auto Zone and they'll scan the truck for you for free. If it's the speed sensor, that's not hard to replace, just unclip the wire harness and remove the old speed sensor on the left rear side of the put put shaft to the transmission. Auto zone caould give you more finer details on to how to do it your self instruction.
The fuel gauge sensor is a part of the fuel pump and that's going to be costly. If your luck it could just be a stuck float and in time the float me start working again. The other thing to is to check the wire harness from the frame rail to the gas tank, after time the winter salt carrodes the connection and it may need to be replaced.
I found most of the time when we work on changing the fuel pump, 65% of the time it's only the wire harness and the pump is fine. But customers always get the new pump and wire harness. 
Good luck and hope this helps.

Speedometer and Odometer quick working. How do I

Follow the speedometer cable from the firewall, down to the transmission. It should bolt in the transmission, remove the cable from the transmission, and turn the gear to check to see if speedometer is working, if not, it's most like the speedometer head unit.

My speedometer quit but the odometer still works (1998 F150) can you solve this

Usually it's the opposite. The speedometer works and the odomater and trip meter go inop. Most likely the speedometer assembly is bad. If the odometer is working you have a signal from the gray and black wire .

Get a Beck Arnley alternator. The auto-zone, Napa etc. alternators are a problem for Isuzu's. I worked at a dealership and a lot of them came in for this problem. If you still have the original have it rebuilt. Check yellow pages.
