In a 1991 Toyota Previa, the primary temperature sensor, often referred to as the coolant temperature sensor, is located near the engine block, typically on the cylinder head or near the thermostat housing. There may also be an additional temperature sensor for the engine management system, which is usually in the same area. For the interior climate control, the temperature sensor is located in the dashboard, monitoring cabin temperature. Always refer to the vehicle's service manual for exact locations and specifications.

Why is your 91 Toyota Previa idling high?

A 1991 Toyota Previa may be idling high due to several reasons, including a vacuum leak, a malfunctioning idle air control valve, or issues with the throttle position sensor. Another possibility is a dirty or faulty mass air flow sensor, which can disrupt the air-fuel mixture. It's also worth checking for any issues with the engine's coolant temperature sensor, as incorrect readings can affect idle speed. Regular maintenance and diagnostics can help identify and resolve the issue.
