Circuit Description
WARNING: This page is about a different car, the 2004 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
The A/C amplifier monitors signals from the speed sensor via the combination meter.
The A/C amplifier assy uses these signals to revise the ambient temperature sensor signal.
Check that the speedometer in the combination meter operates normally before inspecting the vehicle speed signal circuit.
If the meter does not operate normally, refer to the combination meter system (see HOW TO PROCEED WITH TROUBLESHOOTING ).
