1993 Toyota T100 ProblemsDriveability Concerns Due to Throttle Position Sensor Out of Adjustment
The Throttle Position Sensor can get out of adjustment due to wear in the throttle body or due to carbon build up. This will cause the idle timing to advance more than 30 degrees which will cause very high HC and NOx emissions. Conversely, the Throttle Position Sensors can wear out and not properly advance the timing which causes a lack of power and poor fuel economy.
At higher mileages (125,000 -150,000) the power steering pump may begin to leak on the 6 cylinder vehicles and could require replacement.
Our technicians report that by 100,000 miles, the ignition key tends to wear out and should be replaced or it may not work as well in the door locks or ignition lock cylinder.
