Is an unusual code causing your check engine light to come on? The code reader says it could be a sensor, or it could be a connection, or it could be a bad computer. Do you or your mechanic just start replacing parts? Well, that could get expensive. In fact, you could have replaced sensors and computers until the cows come home on this Toyota Rav4, but no parts would fix this problem.
This 2009 Toyota RAV4 V6 had an issue. Ted, a Wattsburg, PA, client, stopped to see the electrical experts at ENORMIS and spoke with Doug. Ted had a “check engine light” on and a “traction control off” light on, and the only code that his mechanic could come up with was a brake booster sensor failure.
This was not making sense to technician Ken Whiteman. Ken scanned the vehicle and there was also a code for a knock sensor malfunction. The knock sensor was offline from the vehicle, which turned the check engine light on, which in turn told the vehicle to turn off the traction control.
Ken took the time to trace wires and was able to track down a chewed wiring harness. No computer can tell you where a rodent chewed a wire!
Doug ordered a new wire harness and Ken installed it and re-assembled the engine the next day. After the repair was completed, Ken test-drove the vehicle to make sure all vehicle systems were functioning. He even re-scanned the vehicle to see if any codes came back. The Toyota Rav4 was repaired without guessing.
