CORRECTIVE ACTION
Error Code 1123 - Intake Manifold Pressure
Sensor Circuit Failure
1. Ensure that ignition switch is
in OFF position. Disconnect
engine harness from intake
manifold pressure sensor
(WP 0093 00).
2. Inspect engine harness and
sensor connector for dirty,
corroded,
bent,
broken,
pushed back, and extended
pins.
Clean and repair connector(s) as

connector. Replace missing or
damaged connector seals (WP
0111 00).
4. Install breakout cable. Place
ignition
switch
in
ON
position.
Check
intake
manifold pressure sensor
supply
voltage.
Check
voltage between lead A and B
of breakout cable. Voltage
should be 4.75-5.25V.
If voltage is not as specified,
proceed.
