Review on 22204 31020 Highlander Corolla Replace 22204 0H010 by Ray Richards

This didn't solve my problem but luckily I left it fitted. I have codes 102 and 113 which are marked as permanent which means they can only be cleared by the ECU itself after a certain number of successful rides. This means that the cause of the codes was primarily temporary, they are not marked as current so they are not occurring now. I believe they can indicate a bad ECU if the code never clears. Both codes relate to components that are part of the MAF assembly. At the same time I received a P500 car speed sensor code which is also permanent. No matter what, it's encountered a number of things, none of the speed sensors are okay. The mice romped around the car for a while and ate three wires from the ABS sensor, but no other wire damage was found anywhere.
