Where is the outside temp sensor on a Saab?
ACC uses different sensors, the outside air temp, the little sensor in the middle of the dashboard by the windscreen (sunlight sensor), internal air temp to calculate what temp air to supply to the cabin, if the outside is warm it will blow cold, if the outside is cool it will blow warm, without you having to change the temp on the ACC controller.
Why is the temp gauge bias on my Saab?
Hard to tell. The analogue temperature signal from the sensor is digitalized by the ECU, transmitted on the P-bus to CIM which puts it on the I-bus to MIU, where the needle of the coolant gauge is controlled by a stepping motor. The “bias” now seen could be caused by the process in the ECU, wiring or the stepping motor of course.
Why is my coolant sensor not working properly?
The culprit can be a bad contact or wiring Coolant Sensor / Engine Control Unit (ECU), and of course the coolant sensor – which is fairly easy to check. Note the enclosed table, measure sensor resistance at connector pin #1 and -2, and extrapolate values if so needed:
Can a faulty temperature sensor cause an air conditioner to not work?
If this sensor is defective, your air-conditioner will not work properly, and you will not have the appropriate temperature in the cabin, which can be very uncomfortably.
Can a temperature sensor be replaced on a Saab?
Replacement is done on model Saab 9-5, but it is almost the same as on other Saab cars. And, Fyi if the sensor not working the a/c will not work.
