2005 Toyota Matrix check engine light on
Lance’s question:
“My 2005 Toyota Matrix had the check engine light on. The code was P2118, something about the throttle actuator motor. So I had the motor assembly changed out, but the code is still there. Have you seen this before?”
Answer:
Yes, that code is for a problem in the throttle motor system, but can be either a problem in the wiring, the actuator motor itself, or the main computer (ECM.) It often is the actuator motor assembly, but the last one I fixed required a new main ECM to fix. The circuitry inside has shorted out.
