P0033-SURGE VALVE SOLENOID CIRCUIT —
TEST
3 Turn the ignition off.
Disconnect the Surge Valve Solenoid harness connector.
Using a 12-volt test light connected to ground, probe the (A142) ASD Relay Output
circuit in the harness connector.
Turn the ignition on.
With the DRBIII , actuate the ASD Relay.
Does the test light illuminate brightly and flash on and off?
Yes → Go To 4
No
4 Turn the ignition off.
Disconnect the Surge Valve Solenoid harness connector.
Disconnect the PCM harness connectors.
Turn the ignition on.
Measure the voltage of the (K150) Surge Sol Control circuit in the Surge Valve
Solenoid harness connector.
Does the voltmeter indicate any voltage present?
Yes → Repair the short to voltage in the (K150) Surge Sol Control circuit.
No
5 Turn the ignition off.
Disconnect the Surge Valve Solenoid harness connector.
Disconnect the PCM harness connectors.
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 (K150) Surge Sol Control circuit from the Surge Valve
Solenoid harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
Yes → Go To 6
No
6 Turn the ignition off.
Disconnect the Surge Valve Solenoid harness connector.
Disconnect the PCM harness connectors.
Measure the resistance between ground and the (K150) Surge Sol Control circuit at
the Surge Valve Solenoid harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the (K150) Surge Sol Control circuit.
No
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.

ACTION
→ Repair the (A142) ASD Relay Output circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC.
→ Go To 5
→ Repair the open in the (K150) Surge Sol Control circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC.
→ Go To 7
Replace and program the Powertrain Control Module in accor-
dance with the Service Information.
