SOURCE: 1998 saturn sc2 P0303 code just came up. already

p303 is a cylinder 3 missfire I woul first check the coil and then the ingnition module, Then if this dont work you could have a bad injector. If after testing and still no fix you should check the compression in that cyl.

First, if you have access to a scan tool, check the reading of the coolant sensor. Does it read a logical number? If so, the problem is likely intermittent. Perform a "wiggle" test by wiggling the connector and harness to the sensor while watching the reading on the scan tool. Watch for any drop-outs. Drop-outs would indicate a bad connection. If the scan tool reads an illogical temperature, check the resistance of the temperature sensor. If it is out of specs, replace it. If it is in specifications, unplug the sensor and, using a fused jumper wire, jumper the two terminals of the connector together. The temperature reading should now be maxed out to above 250 degrees F. If not, there is likely a problem with the ground circuit or voltage supply.
Check for 5 volts reference voltage at the connector. Also check for ground presence at the connector. If you do not have 5V ref. and/or ground continuity, check for these back at the PCM connector. If you have these at the PCM connector, then repair open or short between the PCM and the sensor. If you do not, remove the offending wire from the PCM and then check for proper voltage at the PCM pin. If it's present now, repair short on the circuit. If it isn't present after removing the wire and checking the pin, replace PCM

Possible Causes
The following are malfunctions that could cause a rich condition:
^ Fuel pressure too high. Perform fuel pressure test.
^ Leaking fuel injector(s). - Perform pressure leak down test.
^ Vacuum leak around the MAP sensor grommet.
^ Oxygen sensor contamination.
^ Restricted exhaust or air intake.
^ Fuel Vapor Canister saturated with fuel.

IMPORTANT:
If the front oxygen reading voltage is above 600 mV and the rear HO2S is above 600 mV all the time, the O2 sensors are probably not
at fault.

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
Yes
No
Schematic Reference: Instrument Cluster Schematics
1
Did you perform the Instrument Cluster Diagnostic System Check?
Go to Step 2
Go to Diagnostic System Check - Instrument Cluster
2
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
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.

Where is the engine temp sensor located in a 94 dodge spirit. 2.5 liter car


It doesn't show an 'engine temperature sensor' for that year, make and model
What you do have is a Coolant Temperature Sensor (there are actually one of each on other makes and models - an engine temperature sensor and a coolant {radiator fluid} sensor). Just doesn't appear to be a separate engine temp sensor for the 94 2.5. The coolant temperature sensor is the sensor that will make your temp gauge in the car move. It's location is - Under hood, center, front engine area, near distributor, mounted in driver side of cylinder head. I've attached a pic of the sensor for you.

You also have an intake air temperature sensor and an ambient air temperature sensor that tells the computer the temp in the vehicle's cabin. I can shoot you that info if your question wasn't answered above.



Good Luck & All The Best, Justin Lee

I have 2005 monte carlo it keeps over heating the cooling fans are not comming on I replaced the relays and its still over heating and I can't find the heat senser any help


The coolant temp sensor is on the thermostat housing at the back of the engine. See pictures below. Try taking the connector off the sensor--this should turn the fans on. If not, you may have a problem with power distribution to the fans. You can interrogate the relay sockets to verify that the PCM is sending a signal to turn the fans on. Please see my tip at http://www.fixya.com/cars/r6022358-relay_check on how to interrogate the relays. The PCM signal is a ground signal, so one of the socket terminals should be dead until the engine is hot--then it should become a ground. I have pasted the wiring diagrams below, but resolution on FixYa is not great. Please let me know if you have any questions.

The fans are turned on by the PCM, if the PCM is not telling the fans to turn on, they won't even if everything tests fine.

Coolant Temperature Sensor/Switch (For Computer): Service and Repair
ENGINE COOLANT TEMP SENSOR
REMOVAL
The Engine Coolant Temperature (ECT) sensor (3) on the 5.7L engine is located under the air conditioning compressor. It is installed into a water jacket at the front of the cylinder block.
WARNING: HOT, PRESSURIZED COOLANT CAN CAUSE INJURY BY SCALDING. COOLING SYSTEM MUST BE
PARTIALLY DRAINED BEFORE REMOVING THE COOLANT TEMPERATURE SENSOR.
1. Partially drain the cooling system.
2. Remove accessory drive belt.
3. Carefully unbolt air conditioning compressor from front of engine. Do not disconnect any A/C hoses from compressor. Temporarily support
compressor to gain access to ECT sensor (3).
4. Disconnect electrical connector (2) from sensor (3).
5. Remove sensor (3) from cylinder block.
INSTALLATION
1. Apply thread sealant to sensor threads.
2. Install ECT sensor (3) to engine.
3. Tighten sensor to 11 Nm (97.3 inch lbs.) torque.
4. Connect electrical connector (2) to ECT sensor (3).
5. Fill the cooling system.

I always have to turn on my ac so that the fan can cool my engine


never seen a saturn in my life ,but if it is a 1999 model then it should be in the radiator ,only newer cars have them in the head ,but their are exceptions to this rule but few and far between and mainly *** or french
