2003 Saturn L300 indicator lights stay on: ABS, SES...etc
I took my car 2003 Saturn L300 V6 in for service, as the SES light was on. Went to auto zone and there were several codes..O2 sensor, Coolant sensor etc. Don't recall codes. Had both replaced. SES light still showing coolant sensor code. Took back to mechanic to check. Shortly afterwards, ABS light started coming on. I noticed when the light comes on, all the indicator needles flip to left...fuel goes to empty, speed to zero etc. Then it goes back to correct setting. This flipping occurs constantly. Emerg Brake light stays on for awhile after releasing it.etc. All kinds of issues on the indicator panel. Now I noticed my horn is weak. Dealer suspects computer problem but will diagnose for $95/hr. Usual Mechanic cannot figure out what's going on. Sound familiar to anyone???

First problem, went to autozone. the guy that looked at your car was making pizzas last week. they pull codes and sell you every part you will buy. take the car to the saturn dealer and replace the bcm.

ok lets start with the codes they say your getting. P??? which 1's and how many. there are few o2 sensors, are they next to the Exhaust next to the converter? MASS AIR FLOW -MAF use this, for now i am guessing, until i see the correct codes your are getting. this could be the 1 you may have below, please read it........
Faulty mass air flow sensor
- Intake air leaks
- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor circuit poor electrical connection
Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.
possible symptoms Engine Light ON (or Service Engine Soon Warning Light)
- Engine stall
- Engine running rough
- Excessive fuel consumption
- Excessive smoke
the code is generated when An excessively high voltage from the sensor is sent to Engine Control Module (ECM).
There are several things that could be wrong. The problem with an Auto Zone scanner is that it's just a code reader. You'll need to troubleshoot the engine. Start by looking for a vacuum leak. Are the fuel and air filters clean? How about plugs and wires?
Disconnecting the battery should reset it but I would bet that the light will come back on. I would have a auto parts store read the error code for you. They can also reset it. There are two o2 sensors on this car one on the manifold and one down stream from the converter. If you are getting an o2 error code it could also be the converter.
Catalyst System Low Efficiency (Bank 1)
Air leaks at the exhaust manifold or in the exhaust pipesBase engine problems (i.e., high engine oil or coolant usage.)Catalytic converter is damaged, contaminated or it has failed.Continuous engine misfire conditions, or weak or low coil output.Front HO2S or rear HO2S is contaminated with fuel or moisture.Rear HO2S is loose in the mounting hole (check it for a leak).Front HO2S older (aged) than the rear HO2S (HO2S-12 is lazy) .Here is what is listed in the Saturn repair guide.
That is the sensor in front of the cat converter, either use a 7/8 combination wrench or a o2 sensor wrench . unplug it screw it out. (may need to soak threads w/liquid wrench) Install new sensor. If SES light is on go to Auto Zone. Advance auto to have codes cleared, they normally don't charge.
P0440 code is EVAP control system problem.This has to do with emissions from the carbon can, fuel tank and general leaks that come from fuel evaporation. Anywhere gas fumes can escape the systerm. This code is very common and can be caused by a simple fuel cap being loose or leaking. Check the fuel cap and reset the coputer. If the SES light comes back on there could be a problem with some of the systerm controls. ie vent valve,purge valveand canister. And /or vac leaks.
