2) Check for proper connection of MAP
sensor at “LT GRN/YEL” and “BLU/YEL”
wire
terminals.
3) If OK, then with ignition switch ON, check
voltage at each of “LT GRN/RED” and
“LT GRN/YEL” wire terminals and body
ground. See Fig. 1.
Is voltage about 4 – 6 V at each terminal?
Go to Step 4.
“LT GRN/RED” wire open
or shorted to ground circuit
or shorted to power circuit,
“LT GRN/YEL” wire open
or shorted to ground, poor
C23-25 connection or
C23-31 connection.
If wire and connection are
OK, confirm that MAP
sensor is normal and then
substitute a known-good
ECM and recheck.
NOTE: When battery
voltage is applied to “LT
GRN/RED” wire, it is pos-
sible that MAP sensor is
also faulty.

Is it in good condition?
“LT GRN/RED” wire
shorted to “LT GRN/YEL”
