- Raise vacuum in vacuum unit in throttle housing to release spring. In addition, disconnect intake boot at throttle housing so throttle valve can be moved by hand.
- Ensure ignition is off. Disconnect ETS ECU. Measure resistance between ETS ECU connector terminals No. 20 (Green wire) and No. 21 (Green/White wire). Move throttle valve slowly through its entire travel, allowing it to stop at each point so resistance readings can stabilize. Resistance should be less than 200 ohms. If resistance is within specification, go to step 4). If resistance is at any time greater than 200 ohms, go to step 3).NOTE: It is normal for resistance to increase greater than specification while motor is rotated. This is because of brushes moving along the commutator. Compare resistance to specification only with throttle valve held stationary.
- Disconnect throttle housing connector. Measure resistance of motor between throttle housing terminals No. 1 (Green wire) and No. 7 (Green/White wire). If resistance was greater than 200 ohms in step 2) but is to specification now, check and repair wiring as necessary. If resistance was too high in both tests, replace throttle housing.
- Check Green wire between throttle housing terminal No. 1 and ETS ECU terminal No. 20 for an open or short circuit. Also check Green/White wire between throttle housing terminal No. 7 and ETS ECU terminal No. 21 for an open or short circuit. If wiring is okay and fault code persists, replace ETS ECU.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
