Year of Manufacture *: 2005 Engine Code or CC *: SE17 ( Optional ) Scanner Used: IDS
Hi RX8 2005 JMZSE173600127402 We have an rx8 in with fault code P0661 intake manifold tuning valve control circuit low bank 1. We tried to purchase a days info on mazdas site but problem with pay pal acc. Will try again Wednesday. Anyone got any wiring diags/ pin info for ECU etc We have swopped the 2 valves over but still same. Regards Peter
DETECTION CONDITION • The PCM monitors the SSV solenoid valve control voltage when the PCM turns the SSV solenoid valve off. If the control voltage is less than 5.8 V, the PCM determines that the SSV solenoid valve control circuit voltage is low. Diagnostic support note
• This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. • PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory. POSSIBLE CAUSE • SSV solenoid valve malfunction • Connector or terminal malfunction • Open circuit in wiring harness between main relay terminal C and SSV solenoid valve terminal A • Short to GND in wiring harness between main relay terminal C and SSV solenoid valve terminal A • Open circuit in wiring harness between SSV solenoid valve terminal B and PCM terminal 1L • Short to GND in wiring harness between SSV solenoid valve terminal B and PCM terminal 1L • PCM malfunction
Diagnostic procedure
STEP
INSPECTION
ACTION
1 VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
• Has FREEZE FRAME DATA been recorded? Yes Go to the next step. No Record the FREEZE FRAME DATA on the repair order, then go to the next step. 2 VERIFY RELATED REPAIR INFORMATION AVAILABILITY
• Verify related service repair information availability. • Is any related repair information available? Yes Perform repair or diagnosis according to the available repair information. • If the vehicle is not repaired, go to the next step. No Go to the next step. 3 INSPECT SSV SOLENOID VALVE CONNECTOR FOR POOR CONNECTION
• Turn the ignition switch off. • Disconnect the SSV solenoid valve connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction? Yes Repair or replace the terminal, then go to Step 9. No Go to the next step. 4 INSPECT SSV SOLENOID VALVE POWER CIRCUIT FOR OPEN CIRCUIT OR SHORT TO GND
• Turn the ignition switch to the ON position (Engine off). • Measure the voltage between SSV solenoid valve terminal A (wiring harness-side) and body GND. • Is the voltage B+? Yes Go to the next step. No Repair or replace the wiring harness for a possible open circuit or short to GND, then go to Step 9. 5 INSPECT SSV SOLENOID VALVE CONTROL CIRCUIT FOR SHORT TO GND
• Turn the ignition switch off. • Inspect for continuity between SSV solenoid valve terminal B (wiring harness-side) and body GND. • Is there continuity? Yes Repair or replace the wiring harness for a possible short to GND, then go to Step 9. No Go to the next step. 6 INSPECT SSV SOLENOID VALVE
• Inspect the SSV solenoid valve. (See SECONDARY SHUTTER VALVE (SSV) SOLENOID VALVE INSPECTION.) • Is there any malfunction? Yes Replace the SSV solenoid valve, then go to Step 9. (See INTAKE-AIR SYSTEM HOSE ROUTING DIAGRAM.) No Go to the next step. 7 INSPECT PCM CONNECTOR FOR POOR CONNECTION
• Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction? Yes Repair or replace the terminal, then go to Step 9. No Go to the next step. 8 INSPECT SSV SOLENOID VALVE CONTROL CIRCUIT FOR OPEN CIRCUIT
• Turn the ignition switch off. • Inspect for continuity between SSV solenoid valve terminal B (wiring harness-side) and PCM terminal 1L (wiring harness-side). • Is there continuity? Yes Go to the next step. No Repair or replace the wiring harness for a possible open circuit, then go to the next step. 9 VERIFY TROUBLESHOOTING OF DTC P0661 COMPLETED
• Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine. • Is the PENDING CODE same as DTC present? Yes Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION.) No Go to the next step. 10 VERIFY AFTER REPAIR PROCEDURE
• Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE.) • Are any DTCs present? Yes Go to the applicable DTC inspection. (See DTC TABLE.) No DTC troubleshooting completed.
This is from workshop manual there is a diagram of connections but I cannot upload it if you can supply a fax no I can send it tomorrow HTH Kevin Williams kevi Williams
