Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel Cut Control System Inspection
- This inspection has to be performed after the Fuel Injector Operation Inspection.
If data monitor function of M-MDS is used:
- Warm up the engine and idle it.
- Connect the M-MDS to the DLC-2.
- Select the RPM and the FUELPW PIDs. (See ON-BOARD DIAGNOSTIC TEST .)
- Monitor both PIDs while performing the following steps:
- Depress the accelerator pedal and increase the RPM PID to 4, 000 RPM.
- Quickly release the accelerator pedal (brake pedal is not depressed) and verify that the FUELPW PID is 0 msec, and 2-5 msec when the RPM PID drops below 1, 200 RPM.
- If not as specified, inspect the following:
- ECT sensor No. 1 and related wiring harness (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTION .)
