P1510

FOR ADDITIONAL INFORMATION NOT INCLUDED HERE, REFER TO TSB # 00-T-44 DATED August 01, 2000.

Throttle Control System:

The ECM determines the exact position of the throttle butterfly with the use of two independent oppositely sealed sensors. This code is associated with a range check. If either sensor signal exceeds the upper or lower limit for a short period of time, the DTC will set. This indicates the throttle butterfly is outside of its acceptable range of position. The ECM requests temporary safety fuel deactivation and the vehicle enters a limp home state. Normal throttle operation may resume after a fault is recorded, in which case the vehicle is returned to its normal drive mode.
