Check engine light and Codes

Hi Larry,

Odometer reading?

1. When you replace the fuel filler cap, turn it clockwise until you get at least one click.

2. In a private msg, you indicated the DTC is P2103 and P2111. Both of these DTC are logged by the engine ECU and relate to the throttle motor. DTC P2103 means that the throttle control motor current is 10A or more (which is excessive and means the motor is bogged down) while DTC P2111 means that the throttle control motor is locked when the engine ECU orders the throttle to be opened.

You need to have the throttle plate and throttle body interior cleaned. When the car is IG-OFF, remove the air cleaner cover, then look down into the throttle body interior. Try rotating the spring-loaded throttle plate shaft with your hand. You should be able to easily rotate this 90 degrees so the throttle plate can open and you can see into the intake manifold.

If you cannot rotate the shaft, then you can either try to DIY by buying throttle body cleaner and spraying the interior of the throttle body and throttle plate to clean off the accumulated black gunk and lubricate the throttle shaft, or else you can have your Toyota dealer svc dept do that for you.

While the air cleaner cover is off, remove the air filter and look at the bottom to see how much dirt has accumulated. Hold the filter up to sunlight, and if you cannot see light passing through, replace the filter.

After cleaning off the throttle shaft and ensuring that it rotates freely, if you still have trouble with the check engine light coming on and the same DTC being logged, then you will have to replace the throttle motor. Good luck.

I recommend you try to rotate the throttle shaft with your hand while the car is IG-OFF to see whether the shaft rotates freely or not.

22030-21020 is the part number for the throttle body including motor. The part has an MSRP of $875 and costs $665 here plus shipping:
