I was playing with the computer scan tool yesterday and I noticed that the TPS only went to 75% at WOT? My 04 is cable drive thankfully and not fly by wire, but that just seems weird to me. Anyone else notice something different? Stephen |

Normal. Quote: The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from .26 volts at minimum throttle opening (idle), to 4.49 volts at wide open throttle. The PCM needs to identify the actions and position of the throttle blade at all times. This information is needed to assist in performing the following calculations: † Idle (learned value or minimum TPS) † Off-idle (0.06 volt) † Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage) † Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage) Just some info from the FSM,in bold is why for your reading. |
