1998 Toyota T100 Problems

Vehicle Won't Crank Due To Starter

If the engine will not crank over, the most common problem is the starter. These will tend to go out at about 100,00-125,000 miles. Sometimes it is only the starter solenoid, but often the complete starter (including solenoid) needs to be replaced.

Engine Coolant Temperature Sensor May Stop Working at Higher Mileages

At higher mileages (125,00+) the Engine Coolant Temperature Sensor may intermittently stop working, especially when the vehicle is fully warmed up. This can result in illumination of the Check Engine Light and/or an engine stalling problem.

Lean Mass Air Flow Sensor Causing Code P0170

Occasionally, the mass air flow sensor can go lean and set a code P0170 for fuel system lean. This in not an oxygen sensor problem. If there are no vacuum leaks, the mass air flow sensor may need to be replaced. Our technicians remind us to use a factory part because the aftermarket rebuilds are very inconsistent.
