PARTS INFORMATION:





REQUIRED TOOLS & MATERIAL

REPAIR PROCEDURE:

STEP 1:
Disconnect the negative battery terminal.

STEP 2:





Remove and replace the ECM as per instructions in the Repair Manual.

STEP 3:

1. Connect a hand held vacuum pump to the throttle opener and apply vacuum.





2. Verify that the throttle lever contacts the throttle stop screw with no clearance between the two as shown in Repair Manual.





3. Then verify that the accelerator cable, from the accelerator pedal or from the cruise control unit, is not overly tight at the throttle body adjustment.

NOTE:
- There should be enough play in the cable so that with the throttle fully closed the cable housing can be moved without moving the throttle valve.
- The cable should not seem taut to the touch.

4. Once you have finished this inspection and adjustment verify that the throttle can achieve a fully open position.

STEP 4:

1. Remove and inspect all spark plugs for carbon fouling.
2. Remove and inspect all 4 fuel injectors. If the injector holes have a stain, replace all 4 injectors. Fuel injector removal and installation instructions can be found in the 2001 Camry Repair Manual, Pub. No. RM819U, Volume 2.(Also on ETAS Library)
3. Install and torque all spark plugs.
4. Add one can of Fuel Injector Cleaner P/N C0009-00100 into fuel tank.

STEP 5:

Replace the negative battery cable and tighten. Follow driving instructions found on Fuel Injector Cleaner label to facilitate the removal of carbon. Then restart and drive the vehicle at least one more time to verify proper operation of all components and correction of M.I.L. "ON" condition.

NOTE:
In the interest of ensuring a satisfying ownership experience for our customers, ensure that they are aware of the following information:
- This vehicle is designed to run best on name brand regular fuel (87 Octane).
- Attempting to start the vehicle with the accelerator pedal depressed can lead to some amount of misfire and possibly contribute to causing a M.I.L. "ON" condition.
