TEST

ACTION

APPLICABILITY

1

Ignition on, engine not running.
With the DRBIII

t, read DTCs and record the related Freeze Frame data.

Is the Good Trip displayed and equal to zero?

All

Yes

→ Go To 2

No

→ Refer to the INTERMITTENT CONDITION symptom in the

Driveability category.
Perform POWERTRAIN VERIFICATION TEST VER - 5.

2

Turn the ignition off.
Disconnect the Short Runner Valve Solenoid harness connector.
Turn the ignition on.
Using a 12-volt test light, connect one end to the ASD Relay Output circuit and the
other end to the SRV Solenoid Control circuit.
With the DRBIII

t, actuate the SRV Solenoid.

Does the 12-volt test light flash on and off.

All

No

→ Go To 3

Yes

→ Replace the Short Runner Valve Solenoid.

Perform POWERTRAIN VERIFICATION TEST VER - 5.

ACTION

APPLICABILITY

3

Turn the ignition off.
Disconnect the SRV Solenoid harness connector.
Turn the ignition on.
Using a 12-volt test light connected to ground, check the ASD Relay Output circuit.
With the DRBIII

t, actuate the SRV Solenoid.

Does the 12-volt test light illuminate?

All

Yes

→ Go To 4

No

→ Repair the ASD Relay circuit.

Perform POWERTRAIN VERIFICATION TEST VER - 5.

4

Turn the ignition off.
Disconnect the PCM harness connector.
Disconnect the SRV Solenoid harness connector.
Measure the resistance between the SRV Control circuit and ASD Relay Output
circuit in the SRV Solenoid connector.
Is the resistance below 5.0 ohms?

All

Yes

→ Repair the SRV Control circuit short to the ASD Relay Output

circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.

No

→ Go To 5

5

Turn the ignition off.
Disconnect the PCM harness connector.
Disconnect the SRV Solenoid harness connector.
Measure the resistance between ground and the SRV Control circuit at the SRV
Solenoid harness connector.
Is the resistance below 100 ohms?

All

Yes

→ Repair the short to ground in the SRV Control circuirt.

Perform POWERTRAIN VERIFICATION TEST VER - 5.

No

→ Go To 6

6

Turn the ignition off.
Disconnect the PCM harness connector.
Disconnect the SRV Solenoid harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the SRV Control circuit from the SRV Solenoid harness
connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?

All

Yes

→ Go To 7

No

→ Repair the open in the SRV Control circuit.

Perform POWERTRAIN VERIFICATION TEST VER - 5.

7

NOTE: Before continuing, check the PCM harness connector terminals for
corrosion, damage, or terminal push out. Repair as necessary.
If there are no possible causes remaining, view repair.

All

Repair

Replace and program the Powertrain Control Module Module in
accordance with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 5.

ACTION

APPLICABILITY

1

NOTE: Diagnose any TP Sensor or MAP Sensor component DTCs before
continuing.
NOTE: If the P0501 - No Vehicle Speed Signal is set along with this DTC,
refer to the P0501 diagnostics before continuing.
NOTE: The throttle plate and linkage must be free from binding and carbon
build up, ensure the throttle plate is at the idle position, ensure the throttle
plate is at the idle position.
Ignition on, engine not running.
With the DRBIII

t, read DTCs and record the related Freeze Frame data.

Is the Good Trip Counter displayed and equal to zero?

All

Yes

→ Go To 2

No

→ Refer to the INTERMITTENT CONDITION symptom in the

Driveability category.
Perform POWERTRAIN VERIFICATION TEST VER - 5.

NOTE: This code is enabled on engines with a plastic intake manifold and is
intended to shut down the engine if a large crack occurs in the intake
manifold.
NOTE: A large vacuum leak is most likely the cause of this DTC.
Inspect the Intake Manifold for leaks and cracks.
Inspect the Power Brake Booster for any vacuum leaks.
Inspect the PCV system for proper operation or any vacuum leaks.
Were any vacuum leaks found?

All

Yes

→ Repair the vacuum leak as necessary.

Perform POWERTRAIN VERIFICATION TEST VER - 5.

No

→ Go To 3

3

Start the engine.
With the DRBIII

t, monitor the MAP Sensor voltage.

Snap the throttle.
Does the MAP Sensor voltage vary from below 2.0 volts at idle to above 3.5 volts?

All

Yes

→ Go To 4

No

→ Go To 12

4

Ignition on, engine not running.
With the DRBIII

t, monitor the TP Sensor voltage while slowly depressing the

throttle pedal from the idle position to the wide open throttle position.
Does the voltage start approximately at 0.8 volts and go above 3.5 volts with a smooth
transition?

All

Yes

→ Refer to the INTERMITTENT CONDITION symptom in the

Driveability category.
Perform POWERTRAIN VERIFICATION TEST VER - 5.

No

→ Go To 5
