2008 Tacoma - Knock Sensor Limp Mode
We just had a customer bring in an 08 Tacoma with an Automatic Transmission.
The vehicle is not in for a tune, but a complaint of a P0333 Knock Sensor #2 error. The Knock Sensor location is time consuming to get to and we we're asked to disable the code. When the P0333 sets on this Vehicle, Overdrive is also disabled in the Transmission as some kind of LIMP mode.
We have now paid for credits, unchecked the Knock Sensor #2 codes and now no codes are reported via a DTC scan. The Vehicle however remains unable to shift into Overdrive. Its looking like that the Toyota Support for DTC's is simply a turn the light off, rather than disabling code and whatever limp/error modes that may be accompanied by it.
I hope that this is something that can be looked at by the Toyota Developers as we are currently no further ahead than just removing the Check Engine bulb.
Ticket has been opened but I've been told that Tuning issues are no covered under support - I believe this to be a software issue rather than a "tuning issue".
