Why is the temp gauge on my Saab not working?
However is the temperature information used by the ECU for correcting idling speed, controlling radiator fans determinating injection at different phases etc., so if nothing abnormal is seen it may not be the ECU. The stepping motor – tja. Unplug the connector at the sensor, at cold, not running engine, and note any change of the gauge reading .
What happens when engine heats up to operating temp?
As the engine heats up the ring-cylinder mate becomes looser so that the engine will run smoother and easier…but if there is too much wear the combustion gases will begin to blow by the ring-cylinder surfaces and will cause each stroke to lose power.
Is the warm engine undriveable when cold?
This time it started with an idle around 1500rpm, slowly dropped to 1k, then quickly cycled back up to 1500. It did this for a minute or two, then dropped down to the rough idle, which seems to run between 500-800, kind of hunting around. Is there a key sequence that is used to help it learn? The car is undriveable when warm.
Is the upper throttle body of an IAC gunky?
Upper throttle body was gunky but it wiped right off, just a little bit of hard deposits on the upper inside of the throttle plate, which was gunky also. Yes you should have the three screw model IAC that you only need to remove the intake hose to access.
Why does my car have a bad temp gauge?
I also have heat and have noticed nothing wrong with the cooling system. Is this as easy as a temp sending unit? 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.
Why does my fuel gauge always read high?
Sometimes the Temp gauge reads ridiculously high, sometimes the Boost gauge does the same, and sometimes (less frequently) the Fuel gauge reads high. Removing and replacing fuse number 4 sorts the problem, but it returns within about a week.
Why does my computer temp gauge keep going red?
I inadvertently discovered when my battery died, the gauge was reset when I reconnected with a fresh battery. Every few weeks the gauge creeps back into the red, and I disconnect the battery for 30 seconds to reset the gauge. This is a pain, so I wouldn’t mind some advice on how to reset the computer without disconnecting the battery every time.

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.
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:

Why does coolant disappear from the engine reservoir?
Call it antifreeze, a coolant, or even radiator fluid; the purpose is to maintain the engine’s cool. There may be times when the coolant system may fail due to one reason or another. The mystery arises though when magically the coolant disappearing from reservoir is noticed with no potential signs of leakage. Has this happened with your car too?
When do you lose coolant, but no leaks?
It may be happening only when the car is hot when you drive and the coolant is under pressure. Try checking it when it is hot, under pressure and while the engine is running. BustedKnuckles July 6, 2016, 2:02am #8 The coolant pressure test is obviously showing a coolant leak. The system should not lose pressure if there were no leaks.
Can a bad radiator cap cause a leak?
There may be times that the reservoir radiator cap may turn out to be faulty. While this may seem to be a minor issue, it can lead to dire consequences. In normal circumstances, the coolant gets ousted out from the reservoir overflow tube, the moment the engine starts warming up. This leakage is visible and may result from bad reservoir cap.
Why does my Saab 9-3 leak coolant when it is running?
My Saab 9-3 gushes out coolant when I park it. Doesn’t seem to have any dribbly little leaks either when it is running or parked (but I’m not very observant). Doesn’t overheat. Dashboard says “Fill coolant”. The reservoir is empty.

Why does coolant come out of the overflow tube?
While this may seem to be a minor issue, it can lead to dire consequences. In normal circumstances, the coolant gets ousted out from the reservoir overflow tube, the moment the engine starts warming up. This leakage is visible and may result from bad reservoir cap. Go through maintenance tips for consequences of the overfilled coolant reservoir.
