- Disconnect oxygen sensor connector. Remove bolt from exhaust manifold and install CO Test Connector (13-0-090) with Adapter (13-0-100) on exhaust manifold. Connect CO meter and check idle mixture. Ensure CO level is within specification. See «IDLE SPEED & CO LEVEL SPECIFICATIONS»(ref-10047-S22945984012000110700000) table.
- If CO level exceeds specification, check fuel injectors, fuel pressure and coolant temperature sensor. If CO level is less than specification, check idle speed control hoses and connections and check for air leaks. Reconnect oxygen sensor.
TP sensor is not adjustable. For TP specifications, see THROTTLE POSITION (TP) SENSOR SPECIFICATIONS table.
