2006 Isuzu Ascender Problems
The fuel level sensor may fail resulting in erratic reading of the fuel gauge. Sensor replacement is generally required to correct this concern.
A high pitched squeak type noise may be noted from the front axle area. This is commonly caused by a dry axle shaft seal. Grease can be applied to the outside edge of the seal in an attempted to correct the concern. If no change is noted or the noise returns the affected seal should be replaced.
A no start condition may be caused by a failed ignition lock cylinder (the ignition key will not turn). If this occurs the ignition lock cylinder will require replacement.
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.
A no crank condition may occur and the IGN E fuse is blown. If this occurs our technicians recommended 3 places to inspect for wiring issues: Under the sill place at the drivers side rear door opening, along the steering column, and near the brake pedal bracket. Damaged wires will require repair and should be repositioned and protected from further damage.
A squeak noise may be noted upon brake apply. If basic brake inspection procedures don't reveal any faults, our technicians recommend flushing the DOT 3 brake fluid and replacing it with Delco Supreme 11 fluid to correct this concern.
The 4WD warning message may be displayed with a code C0327. The transfer case position sensor is commonly at fault and will require replacement.
The horn may not function at times due to a faulty ground circuit in the steering column. Our technicians tell us that adding a ground strap between the upper and lower steering column mounting points will commonly correct this issue.
