Driveability Concerns Due to Throttle Position Sensor Out of Adjustment on Toyota Land Cruiser

Problem Description and Possible Solution

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.
