Total amount of spark retard commanded by the PCM in response to a
monitored knock.
Tbody Temp Sens (Volts) Range: 0 to 5 Volts
The PCM converts the voltage read from the throttle body temperature
sensor to a temperature (see Throttle Body degrees F).
Throttle Body (° F) Range: -40° to
261°
The Throttle Body temperature indicates the fuel temperature in the
throttle body of Single-Point fuel injected vehicles. This information is
used to avoid vapor lock during hot restarts. The higher the tempera-
ture, the wider the injector pulse width. This is known as the charge
temperature on earlier model vehicles.
Throttle Open (% open) Range: 0 to
100%
The Throttle Open parameter is a relative percentage of throttle open-
ing based on the learned minimum throttle position.
Throttle Posn (Volts) Range: 0 to 5
Volts
The voltage of the sensor mounted on the throttle shaft that relays
throttle position back to the PCM. The throttle position helps determine
the
correct air/fuel mixture. At idle the TPS should read in the 0.5 to 1 volt
range, at Wide Open Throttle (WOT) the TPS should read 4 -5 volts.
Total Spark Advance (° BTDC) Range: -10° to
70°
Total Spark Advance is the PCM base advance summed with specified
mechanical advance.
Trans Fluid Temp (° F)
Starting in 1993, some Chrysler vehicles have a sensor to detect
transmission fluid temperature.
Trans Fluid Sens (Volts) Range: 0 to 5
Volts
The transmission fluid temperature sensor input voltage that the PCM
uses to convert to a temperature.
