CORRECTIVE ACTION
Error Code 1122 - 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,

3. Check engine harness and
sensor connector for dirt or
moisture in or on connector
and for missing or damaged
connector seals.
Remove dirt and moisture from
connector. Replace missing or
damaged connector seals (WP
0111 00).
4. Disconnect all pressure and
temperature sensors from
engine harness. Disconnect
coolant level sensor jumper
wires no. 5 and 6 from 31-pin
OEM connector, located on
left side of engine to rear of
