WARNING: This page is about a different car, the 2003 Mazda Protege5, 2003 Mazda Protege, 2003 Mazda MX-5 Miata, 2003 Mazda MPV, and 2003 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect purge solenoid valve 2-pin harness connector and vacuum hoses. Purge solenoid valve is located by throttle body. See Figure. Ensure air does not flow through purge solenoid valve vacuum ports. Using fused jumper wires. Connect battery voltage to purge solenoid valve terminals. Air should pass through vacuum ports. If purge solenoid valve operates as specified, check for open or short circuit. Go to next step. If purge solenoid valve does not operate as specified, replace purge solenoid valve. Perform the following test only when directed. Disconnect negative battery cable.
- Open Circuit
Disconnect PCM harness connectors. Check continuity between following terminals.- Purge solenoid valve 2-pin harness connector terminal "A" and PCM 30-pin harness connector terminal "4U" (Blue/Yellow wire).
- Purge solenoid valve 2-pin harness connector terminal "B" and main relay terminal "C" (White wire).
If continuity is present, go to next step. If continuity is not present, repair open circuit in suspect wire or replace wire harness. See appropriate WIRING DIAGRAM under ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS.
- Short Circuit
Check for continuity between following:- Purge solenoid valve 2-pin harness connector terminal "A" (Blue/Yellow wire) and body GND
- Purge solenoid valve 2-pin harness connector terminal "B" (White wire) and power supply
If continuity is present, repair short circuit in suspect wire or replace wire harness.
