lower voltage represents a deceleration or cruise condition. The in-Hg
value is determined by converting the MAP sensor input voltage to a
pressure. The lower the MAP the higher the manifold vacuum.
Min Throttle Pos (Volts)
Range: 0 to 5 Volts
This voltage is the idle TPS voltage which is used as a reference by the
PCM. This voltage is the lowest TPS voltage, so that every movement of
the throttle can be detected. This value is usually around 0.8 Volts.
Module Advance (°)
Range: -10° to 70°
Base electrical spark advance as determined by the PCM. The PCM will
use the coolant temperature sensor, engine speed, and vacuum to
determine advance on a cold start. After the engine reaches normal
operating temperature, the PCM will eliminate the coolant temperature
sensor from the calculation.
O2 Bank x/ Pos y (Volts)
Range: 0 to 1 Volts
The oxygen sensor generates an input voltage corresponding to the
amount of oxygen in the exhaust. The oxygen sensor must reach a
certain temperature before the readings are accurate. In closed loop (see
Loop Status) the PCM will use this sensor for air/fuel mixture adjustments.
This reading is the oxygen sensor reading for single oxygen sensor
vehicles. For vehicles with multiple oxygen sensors, (x) refers to the
first (or the only) bank of cylinders and (y) refers to either the pre- or
post-catalytic position of the oxygen sensor. Pos 1 is the pre-catalytic
position and Pos 2 is the post-catalytic position. A value of 0 to .5 Volts
will indicate a lean mixture, a value of .5 to1.00 Volts will indicate a
rich mixture.
O2 Bank x/ Pos y (State)
The PCM will convert the voltage of the corresponding input sensor to a
mixture state of either RICH, LEAN, or CENTER [see O2 Bank x/ Pos y
(Volts)].
Oil Pressure (psi)
This parameter shows the oil pressure.
Oil Press Sens (Volts)
Range: 0 to 5 Volts
The actual oil pressure is converted from the oil pressure input sensor
voltage.
Overall Retard (°)
Range: 0° to 128°
