Heat sensor

where is the heat sensor located on a 1996 dodge caravan

The heater circuit for oxygen sensor bank #1 sensor #1 is slow to respond. This usually means the O2 sensor requires replacing.


where is the sensor located at

Which heat sensor. There will be one or more for the coolant, maybe one for the oil, another for the exhaust then maybe one for the intake air temp …

If you can tell us more, like why you care where it is located, maybe we can give you a better answer.

It’s threaded into the exhaust manifold, firewall side of the engine.
