You Mean the fuel pressure regulator Or fuel tank pressure sensor?? There is a fuel tank pressure sensor on top of fuel tank 98+.

SOURCE: 2001 saturn sc2 gets code 341&340 camshaft sensor

if you have high resistance in secondary ign. system (plug wires, ign.coil) this will cause this code to set. make sure you are using a high quality spark plug wire set. not from autozone!!! and denso non platinum tipped spark plugs. also use a diaelectric grease on plug wires to keep moisture out.

You will have to drop the fuel tank down far enough to access the top of the fuel tank. You will probably have to remove the exhaust system and all hoses and electrical connections. Disconnect the connector from the sensor, pry it out of the top of the fuel pump module. Be careful not to break the top of the fuel pump module. When installing the n

Saturn sc2 problem


DTC P0732 sets when 2nd clutch still slips after the PCM has commanded high main line pressure
DTC P0734 sets when 4th clutch still slips after the PCM has commanded high main line pressure.
DTC P0733 sets when 3rd clutch still slips after the PCM has commanded high main line pressure.
The powertrain control module (PCM) uses the crankshaft position (CKP) sensor, input speed sensor (ISS) and output speed sensor (OSS) to determine engine speed, input shaft speed and output shaft speed. These sensor readings are used to determine the current gear ratio and RPM slip across the torque converter. The PCM uses this information from the sensors to determine if the commanded gear matches the actual gear. During normal driving conditions, the PCM will adapt main line pressure via the pressure control (PC) solenoid to prevent slipping and harsh shifts. Shift solenoid 2 is used to apply or release second gear clutch. The PCM controls 2nd gear by controlling the ground for shift solenoid 2. The PCM will turn the solenoid Off (open the driver circuit) when second gear is commanded On to apply 2nd clutch. Shift solenoid 2 is supplied ignition voltage from the fuel pump relay whenever the PCM commands the fuel pump relay On.
Do you know how to test main line pressure ? Also , with the valve body off air check clutch packs . Do you know how to do that ? How many miles on the trany ?

2002 Saturn SC2 - having fuel system issue. Had the entire fuel system cleaned a year ago (the throttle was sticking). Having heavy exhaust that smells like gas and using more gasoline that normal. The car...


How long since a tune-up? Any applicable trouble codes? If issues are temp related, check your coolant temp sensor. I'm not saying replacing that sensor will definitely fix it?
Also, use a gage and check proper fuel pressure, my info says 38--44 psi. After you bring up the proper fuel pressure, turn off the key. My info says the max fuel pressure drop in 5 minutes is 8 psi. So if the fuel pressure drops like a rock, you have a fuel pressure leak and you need to find it and fix.

P1133 on a 2002 saturn sc2 1.9L


Hi thee:
Check this possible causes:
- Air leaks present in the exhaust manifold or the exhaust pipes
- Fuel pressure is too high (i.e., causing a rich air fuel mixture)
- HO2S may be contaminated (due to improper fuel or silicone)
- HO2S signal high or low reference circuit has high resistance
- HO2S heater element has failed, or the heater circuit is open
- PCM has failed

Test wires and harnesses. Hope helps.

1993 saturn sc2 wile driving car shuts off like you turned off key then it is hard to restart


could be faulty fuel pump or stopped up fuel filter.if you are getting fuel,the idle air control valve stop working, or you have faulty crankshaft sensor and a camshaft sensor,need to code scan vechicle first to see what sensor is faulty.

Have 93 saturn sc2 parked for about 2 years, has new battery and new gas, has power, engine turns over but doesnt fully crank, could fuel pump be problem? if so how much and how big a problem to fix is it?


there are tools to check the line pressure. it is 17 years old and the fuel pump did its job as of 2003. pump is in the gas tank and you have to drop the tank to replace it. lots of work. i would check the line pressure, the injectors could be gummed up after 2 years.

How do i change a fuel filter on a 1994 saturn sc2


Hi, remove gas cap and relieve fuel system pressure from fuel rail pressure relieve valve.Then you will want a drain pan of course. Before you can remove the fuel line, you will have to buy the cheap plastic quick-connect fuel line removal tool that fits your car. Or buy a universal pack for like $5. Then you press the plastic tool inside the fitting and pull on the other side and it disconnects instantly. then grab the new filter and the lines will just click right back in

1993 Saturn SC 2 starts but wont stay running


Engine coolant temp sensor, If you pull it you will be able to see if it is cracked.. I don't know why but the original sensors they designed the ceramic tips crack around the tip of the head.. It will make the car nearly impossible to start smoke when cranking the engine, and idle really rough racey infact. 15 dollars or so let me know if that worked for you

97 saturn sc2


I had the same problem with a 97 sc2. The fix for my car was the temp sensor that controls the extra fuel when engine is cold it didn't sense that the engine was warmed up and added extra fuel flooding the engine.
