DIAGNOSTIC TROUBLE CODE (DTC) P1181
VARIABLE INTAKE MANIFOLD SOLENOID LOW
VOLTAGE
Circuit Description
The Engine Control Module(ECM) operates a solenoid to
control the Variable Intake Manifold(VIM) solenoid electri-
cal. The solenoid is normally closed. By providing a ground
path, the ECM energizes the solenoid.
Conditions for Setting the DTC
S The VIM solenoid circuit is an open or a short to
ground condition exists.
Action Taken When the DTC Sets
S The Malfunction Indicator Lamp (MIL) will illumi-
nate.
S The ECM will record operating conditions at the
time the diagnostic fails. The information will be
stored in the freeze frame and failure records buff-
ers.S A history DTC is stored.
Conditions for Clearing the MIL/DTC
S The MIL will turn off after consecutive ignition
cycles in which the diagnostic runs without a fault.
S A history DTC will clear after 40 consecutive warm
up cycles without a fault.
S DTC(s) can be cleared by using the scan tool.
S Disconnecting the ECM battery feed for 10 sec-
onds.
Diagnostic Aids
An intermittent problem may be caused by a poor connec-
tion, rubbed–through wire insulation, or a wire that is bro-
ken inside the insulation.

StepActionValue(s)YesNo
1Perform an On–Board Diagnostic (EOBD) System
Check.
Is the system check complete?–Go to Step 2Go to
”On–Board
Diagnostic Sys-
tem Check”
21. Turn the ignition switch to LOCK.
2. Disconnect the Variable Intake Manifold(VIM)
solenoid connector.
3. Measure the resistance of the VIM solenoid.
Does the resistance near the specified value?0 WGo to Step 3Go to Step 6
31. Disconnect the ignition relay connector.
2. Check for an open or a short to ground in the
wire between the VIM solenoid connector ter-
minal 2 and the engine connector terminal 13.
Is the problem found?–Go to Step 4Go to Step 5
4Repair the wire and the connector terminal.
Is the repair complete?–Go to Step 8–
51. Turn the ignition switch to LOCK.
2. Disconnect the Engine Control Module(ECM)
connector.
3. Check for an open or a short to ground in the
wire between the VIM solenoid connector ter-
minal 1 and the ECM connector terminal 37.
Is the problem found?–Go to Step 4Go to Step 7
6Replace the VIM solenoid.
Is the replacement complete?–Go to Step 8–
7Replace the ECM.
Is the replacement complete?–Go to Step 9–
81. Using the scan tool, clear the Diagnostic
Trouble Codes (DTCs).
2. Start the engine.
3. Run the engine until it reaches normal operat-
ing temperature at idle.
4. Operating the vehicle within the conditions for
setting this DTC as specified in the supporting
text.
Does the scan tool indicate that this diagnostic has
run and passed?–Go to Step 9Go to Step 2
9Check if any additional DTCs are set.
Are any DTCs displayed that have not been diag-
nosed?–Go to
applicable DTC
