I have had a issue with my 4Runner where it lost the speedometer and odometer, cruise control and the check engine, BRAKE, VSC OFF, VSC TRAC, ABS lights all stay on.
After reading around
this post I replaced the module and it fixed the speedometer, odometer and cruise control issues immediately so that was definitely part of the problem.
I bought a ODB2 reader and cleared the codes out and I am getting a P1135 code, this may have been a issue for a while, It's been about a year since the lights first came on, so it seems like I may have had a few issues going on.
According to the DTC site it shows this info for Toyota and P1135....
P1135 - Toyota
Type: Powertrain - Manufacturer Controlled DTC - Manufacturer Controlled
Description: Air fuel ratio sensor - heater circuit malfunction
Cause: Wiring, air fuel ratio sensor
As far as I can tell it is some sort of sensor that is causing the problem. Has anyone experienced this combination of error codes and lights coming on? It seems odd the BRAKE, VSC OFF, VSC TRAC, ABS lights all come on.
Any tips on what sensor is bad and how to locate it or swap it out is much appreciated. I can do most moderate repairs myself or is this a more complicated fix?
