Question about 2007 Saturn ION-2 Quad Coupe

1 Answer

I have a 2007 Saturn ION 2. I've already had the cam performance sensor replaced. Now something is causing the temperature gauge to malfunction. (Won't move, and then, it kicks up - to normal) The A/C wasn't cool, when the needle on temp moved, the A/C began cooling again. Another sensor bad?

Did you have a specific engine code requiring replacement of the Cam Position Sensor?
Did you recently replace the thermostat or run low on coolant or have some other cooling system work done? The temperature sensor can be bad, or simply have a loose wire connection. Check those. There can be air in the coolant system as well. Finally, the thermostat could be sticking and will need to be replaced.

These issues have nothing to do with the Air Conditioner. However, the AC will not cool if the car is sitting still unless the condenser fans (electric) are running. Turn on the AC and check to ensure the cooling fans energize.

Most of these items you can check yourself, however if not, then have your mechanic or a mechanically inclined family member or friend check them for you.

Best regards,

SOURCE: dashboard gauges

Sounds like a bad ground.

On the back of your instrument cluster is a flat, thin, plastic strip. This plastic strip has thin copper strips in it for wiring. This 'wiring' provides electricity to your gauges, and a ground connection.
(Some gauges have constant power to them, and use the lack of a ground source to provide a reading. Some gauges use the power from the sender unit, and have to have a constant ground source)

There is a ground connection or two, provided by a wire, or wires, from the metal body of your Grand Am. These are screwed to the body by screws that go through an 'Eyelet'. This eyelet is a round terminal with a hole in it. Often the area where the eyelet touches the body, has corrosion in-between it. Or perhaps the screw/s have become loose.

There are also ground straps that come from the engine block to the car body. They are usually at the back of the engine, and connected to the firewall. There must be at least two of these ground straps connected. This is how the body is grounded to the rest of the car. Check these also for looseness, and corrosion.

Sounds like you have a loose wire, probably at the fuse panel for the AC fuse, but be prepared to trace the wiring if the bad connection isn't right at the fuse panel.
Replace the fuse, and see if that clears up the problem.
If it doesn't, measure the voltage on both sides of the fuse so that you can see which direction you have to trace the wiring.
if there's no voltage going into the fuse, start tracing between the ignition switch to the fuse panel.
If there's power to both sides of the fuse, start tracing the wire from the fuse to the AC unit and temperature gauge. Also investigate the temperature gauge itself, as the AC shutoff may be contained within it.
If there is voltage on only one side of the fuse, investigate the fuse itself and the socket in the fuse panel.

Engine temp gauge not reading and ac will not turn on due to engine hot warning, diognostics say its a sensor, need to know which one and can i do it myself?2003 saturn vue

What diognostics say its a sensor ?????? No diagnostic's ever tell's you it's a sensor . You as a technician would need to prove that by testing electrical circuits , viewing coolant temp sensor . Hooking scan tool and trying to command the gauge with by directional control . The temp gauge not showing any temp. ? No movement ? Engine Coolant Temperature Gage Inaccurate or InoperativeStep Action
Schematic Reference: Instrument Cluster Schematics
Did you perform the Instrument Cluster Diagnostic System Check?
Go to Step 2
Go to Diagnostic System Check - Instrument Cluster
Install a scan tool.
Turn the ignition ON, with the engine OFF.
With the scan tool, perform the Lamp and Gauge Check in the IPC Special Functions list.
Does the engine coolant temperature gage move up and down when commanded?
Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems
Go to Step 3
Replace the IPC. Refer to Instrument Cluster Replacement .
Did you complete the replacement?
Go to Step 4
Operate the system in order to verify the repair.
Did you correct the condition?
System OK
Go to Step 2
Would hate for you to replace the coolant temp sensor an find out that's not the problem ! Does the vehicle start an run good ,trans mission shift good ? If so it's not the coolant temp sensor .
Engine Coolant Temperature Gage
The ECM sends coolant temperature as determined by the coolant temperature sensor to the BCM via CAN serial data. The IPC displays the engine coolant temperature with the gage when the BCM sends a class 2 message to the IPC indicating coolant temperature percentage. The engine coolant temperature gage defaults to cold (0°) or below if:
• The ECM detects a malfunction in the engine coolant temperature sensor circuit.
• The IPC detects a loss of class 2 communications with the BCM.
• The BCM detects a loss of CAN communications with the ECM.

Temperature sensing

There should be two sensors - one for the computer and one for the gauge. Are you working on the right one ? Can you ground the sensor plug and make the gauge move ?
Is the engine warming up ?

I have a 1998 Saturn SL2 DOHC with ~140,000 miles. The car runs great, but I am having trouble with the coolant temperature. When first starting the car up in the morning, the coolant temperature gauge...

When you said you replaced everything, did that include the temperature sending unit?
The temperature sensor just operates the cooling fan or fans for the radiator.
The temperature sending unit operates the temperature gauge in the dashboard. If that thing is faulty, the gauge won't work right.
If you did change the sending unit, it could be possible that the computor is screwing it up, but in my 41 years as a mechanic I never heard of it, when a computor goes, nothing works.

My saturn ion stalls when making left hand turn and hasatates this is a 2005 ion 3 already replaced map sensor still stalls

Sounds like a fuel issue to me. Maybe the fuel is sloshing to the right of the tank and causing air to be drawn into the fuel line. Just a guess but something to think about.
