2004 Isuzu Ascender Problems

Fuel Level Sensor May Fail

The fuel level sensor may fail resulting in erratic reading of the fuel gauge. Sensor replacement is generally required to correct this concern.

Harsh transmission shifting due to failed input speed sensor

The transmission may develop a harsh shift condition with the Check Engine Light on and fault code P0717 stored. This is commonly cased by a failed input speed sensor (ISS), located inside the transmission. The wiring at the sensor may be found damaged. If so, the sharp edges near with ISS wiring should be filed smooth to protect the new speed sensor wiring from damage.

Check Engine Light with code P0606

The Check Engine Light may illuminate with a code P0606 stored. Our technicians tell us updating the powertrain control module (PCM) software will generally correct this concern.
