Last year at this time, the problem consisted of over-revving the engine when attempting to reach ~25mph (car threw a P1091 and had no power going up hills). At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. it might be a good idea to buy one of these sensors ahead of time, and keep Excess water found in fuel by water-in-fuel sensor. Driving my 97 Oldsmobile cutlass supreme 3100 engine drove perfectly. This information contains the actions of the driver such as accelerating, power steering and so forth. All vehicles have something called a throttle which controls how much fuel is allowed to flow into the engine. See Also: How Drive-By-Wire Throttle Works.

The PCM supplies approximately 5 volts to the TPS. (Always (Transmission was also said to be in good shape around that same time when checked at an AAMCO.) (Same as code 64). It wants to idle low and die in gear at a stop light. control circuit. Perhaps it wasnt the root cause of the issue. Incorrect input state detected for the power steering switch circuit. The TPS output voltage (input signal to the PCM) represents the throttle blade position. So anytime you step on the gas pedal to accelerate your vehicle, the computer sends this information to the sensor so that the throttle knows how much fuel to let flow into the engine. Now, slowly close the throttle.
