Hi,

To my knowledge, a 2003 Ford Focus 2.0 SPi engine would need 4 quarts of engine oil (roughly 3.78 liters). Incidentally, the Ford/Cosworth Zeta/Zetec engine would be needing 4.25 quarts (~4 liters).

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Hello Bret.
These codes are indicating engine misfires. 303 is cylinder #3 and 304 is cylinder #4. The 316 indicates that the misfire happened in the first 1000 revolutions.
These trucks are notorious for misfires. The most common issue is ignition coil failure. Failure on these coils can be accelerated though by spark plugs that are worn and contamination from oils, antifreeze leaks and water.
If it has been some time since you have replaced the spark plugs this may be an opportune time to do so. This job isn't for the faint of heart or those with little patience. Some of the coils and plugs are difficult to access, especially #7 and # 8. I also recommend torquing the spark plugs properly as there are some thread stripping issues on the spark plug threads with these engines.
Have at least 2 new coil assembly's for the two cylinders that are misfiring and be prepared to find at least one more that looks poor. I have used some aftermarket coils but have had issues with them. Ford has reduced the price on their coils to reflect a more fair market value so I would use those.
Have a look for any contamination issues and repair those to prevent future problems.
Hope this helps you along.

Check and clean the MAF (mass air flow sensor). you will need a #20 anti-tamper torx bit and some carburetor cleaner. Be careful with the sensor it is delicate.

Fault codes PO 193 FRP -- PO 101 MAF -- PO 380 -- PO a 09dc/dc -- PO 238 TURBO/ super charger-- PO 118 ECT -- PO 283 fuel temp sensor -- U 2023 brake sensor


101,380 and 118. These together is a no start. Take it to a garage. Just a guess, but I would be looking into the wiring. You waited to long to have a problem fixed. One bad part over time will lead to many codes. The PCM is trying to adjust to make the engine run right. Throwing other sensor out of range. Out of range pops a code.

I have a 03 ford explorer codes p0307 p0316 what could cause that injects good


You have to use Google to find your codes
& study OBD2 Systems
Forget the PO316
The PO 301 thru PO 308 are engine cylinder misfires
On a 2003 --11 year old ford veh you replace ALL
8 COP Ignition Coils
They only last about 6 to 7 years
Some will set a PO300 code
Some with set lots of codes even with just one bad coil
Some coils are so bad they will shut the engine off anytime
& any where under any conditions or temp
There are alos 3 or more ways to diagnose the coils
With no experience & over 7 years on them,buy all 8 coils
from Rock Auto & replace
Also the front Oxygen Sensors get replaced at 100,000
The last number as in your 307 is cylinder #7
Some fords you have
A,B,C,D,E, etc
1,2,3,4,5 etc
PO 301,302,303,304 etc
All 3 examples are the same thing or cylinders

Ford Focus Engine Light


Start by getting either a mechanic or someone with an OBDII scanner to read the code so you know where to start. Lots of time a loose gas cap will cause a "Evap system small leak" code which illuminates the check engine light for a while. Other than that I can't help you much without knowing what code comes up.
