[Camray All-Trac - O/D indicator blinks]

Error code 44 when diag pins E1 and Tt are jumpered. Rear wheel speed sensor problem.

Not too worried about it since it's summer. I am guessing this sensor is involved in control of the Diff lockup in the event of rear wheelspin?

I'd start by cleaning the throttle body and the ISC/IAC valve first. You can download a manual here....

It doesn't do it all the time, but often my "Overdrive Off" indicator blinks rhythmically. Since it seems to keep a beat fairly well, I am guessing it's an error code being displayed?

Overdrive works properly even with the blinking.

Thanks!

I just bought a 91 Camry All-Trac, and by the time I got it home, it was hot enough to start an idle fluctuation. The engine revs up and down in a rather rhythmical fashion, in neutral and park. If I turn the A/C on, the problem goes away. A/C off and it comes back. If I let the engine cool down for a few hours, the problem goes away.

Any ideas? This is my first Toyota.

The car runs great otherwise.

Thanks!
