Fuel Cut Control System Inspection

Warm up engine and idle it.
Turn off the electrical loads and A/C switch.
Connect the M-MDS to the DLC-2.
Access the RPM PID. (See ON-BOARD DIAGNOSTIC TEST .)
Listen for the fuel injector operation sound at all cylinders using the soundscope and monitor both PIDs while performing the following steps:
1. Depress the accelerator pedal and increase the engine speed to 4, 000 RPM.
2. Quickly release the accelerator pedal (brake pedal is not depressed) and verify that the fuel injector operation sound stops, and starts again when the engine speed drops below 1, 200 RPM.
- If not as specified, inspect the following:
- ECT sensor and related wiring harness (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTION .)
- TR switch and related wiring harness (See TRANSAXLE RANGE (TR) SWITCH INSPECTION [FS5A-EL] .)
