What happens when a misfire occurs on a Saturn?
When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, the Engine Control Module (ECM) can determine that a misfire is occurring.

What does the P0300 Saturn engine code mean?
Start by checking for intake leaks, intake gaskets are commonly caused by multi-cylinder misfiring. If no leak is found the next step is to replace the spark plugs. If the problem persists more tests need to be done to diagnose the problem, see “Possible Causes”. The cost to diagnose the P0300 SATURN code is 1.0 hour of labor.
How much does it cost to repair a Saturn P0300?
The cost of diagnosing the P0300 SATURN code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour. When is the P0300 SATURN code detected?
Where is the trouble code on a Saturn?
These are listed in numerical order for easy searching. When retrieving Saturn trouble codes with an OBD II scan tool, proceed as follows: 1. Connect scan tool to the 16-pin data link connector (DLC) located underneath the steering column. The connector may have a removable cover. 2. Turn the ignition on. 3.
How to check check engine light on Saturn?
Saturn Check Engine Light Codes 1 Connect scan tool to the 16-pin data link connector (DLC) located underneath the steering column. The connector may have a removable cover. 2 Turn the ignition on. 3 Follow scan tool manufacturer’s operating instructions to access the Diagnostic Trouble Codes (DTC’s).

What happens to fuel injector during misfire event?
In Spark Ignition Direct Injection (SIDI) system applications, if a fuel injector fault DTC is set during a misfire event, the ECM will not re-enable the injector. Need more information on how to fix the P0300 SATURN code?
How does the ECM detect a cylinder misfire?
By monitoring variations in the crankshaft rotation speed for each cylinder, the ECM can detect individual cylinder misfire events. Extreme cylinder misfire events can cause catalytic converter damage. The malfunction indicator lamp (MIL) will flash when the conditions for catalytic converter damage are present.
What happens when a fuel injector is misfiring?
When the ECM detects that one or more specific cylinders are misfiring, the DTC for the respective misfiring cylinder will set, and up to 2 of the corresponding fuel injectors are disabled for a minimum of 30 s.

When does a Saturn’s series engine fail?
The aftermarket replacements have a quality problem; best bet is to find a low mileage junkyard replacement or order the OE part (~$70). Not hugely common, but still a recurring failure. They usually fail when the engine is hot. You’ll be driving along, and suddenly the engine dies, and won’t restart until it cools.
What kind of spark plugs do Saturn’s series use?
Most copper plugs fit this description. Narrow fine wire electrodes almost always cause problems, usually a p0300 and running like the car needs new plugs. The easiest thing to do here is just use the OE spark plugs, they’re inexpensive and just work. NGK BKR5ESA-11 (DOHC) and BKR4ESA-11 (SOHC). These have a higher than normal failure rate.
What causes a Saturn’s to slam into reverse?
This causes the car to “slam” into reverse and/or harsh upshifts, depending on which is worn. It will eventually destroy the line pressure solenoid, which will make for very hard upshifts. If left for a while, it will knock the input shaft nut loose, further worsening the condition of the shifts.
Why is my fuel pump not working on my Saturn s?
This is caused mainly by overdrawing from the 12v socket, or high power aftermarket accessories drawing from the same circuit. There will be melted plastic around the fuse. The radio, chime module, dome light, 12v socket, and fuel pump are on this circuit. You will probably know about it when the fuel pump stops working.
