2005 Isuzu Ascender

My check engine light goes on and off. When I bring the car to a mechanic, the computer under the dash will not give a readout. A few have suggested I need a new computer. I am thinking it could be a fuse, where would that be located? I want to get it fixed as the car is running rough and loses power going up hill. Once I accelerate to 60+ mph the car runs smooth. It is also using more gas. I suspect the o2 sensors but I want to be sure.

Tune it up and replace the 02 sensor that keeps setting the codes bank 2 sensor 1. Have your oil and filter changed right before you go for a retest to. That will clear up 3 codes P0300, 0155 and 0154. You might have to replace the fuel sending unit to get rid of P0463 but if the gauge works OK I'd leave it alone.

SOURCE: Fuel Gauge reads empty, but tank IS full

the float in your gas tank seems to have water in it....water is heavier than gas, that's why gas floats on top of water....try putting something like HEAT in it to dry up the water in your tank....

I would change the trans flter, trans fluid, and have the linkage on the trans adjusted.

The upper intake gaskets may be leaking. They are made of plastic and metal and will leak air. Do not remove the cover on very top of manifold when changing.

When it rains the traction assist light comes on, then the check engine light comes on and the downed power light. Our mechanic has checked all of the wiring.


I think that every wheel have the traction sensor so, either one of them is bad or all of them are. Check the front wheel fender and might sure that there is no openings specially close to the fuse box. If the problem persist just take it to your local Isuzu dealer. Good Luck!

The Ascender is the same as a Chevrolet TrailBlazer, GMC Envoy, Buick Rainier, and Saab 9-7X. Look on the Chevy forums for where/how to change this. It should like like this - maybe:

Replace you Gas Cap and see if it will not stop this Problem. If the Seal on the Gas Cap is Bad it will allow air into the Tank and will cause this Problem. Please Rate My Response! Thanks!
