I have a manual on this car, but it does not say where to find the speed sensor for the Loyale. Car has been sitting for years with a blown head gasket. Runs good now after an R&R. Took it for a road test today and the check engine light came on, code 33, speed sensor. I'll do the voltage checks at the ECU in the morning, but where is the sensor actually located on the Loyale?

It's a reed switch in the speedometer head in the instrument cluster.
