Ok, I just purchased my first F car, 00 360 manual with 15k miles. The car has tubi and cats bypassed. The CEL is always on, the dealer said that this is due to cat delete and it wont cause any problems. I have read lots of treads about CEL and understand that unless you remove cats the CEL wont light up (mostly), and vice versa, with no real effect on car (when the CEL is on due to cats). As i have had my other cars modified i know that the CEL comes up with cat delete but i always find ways (produts) to delete it permenantly. However this car is Ferrari so i have to take everything more serious. My main concern is, how can you understand if there is wrong with the engine if the light is always on? Dealer told that the screen on rpm dial will show anything (kinda) out of the ordinary, is that true? I do not think that CEL is only there to warn about emission problems. Do i have to take the car to service every 1k miles or so to check if it signalled a problem which i can not see due to the fact that the light is always on, or the rpm dials screen really helpfull? Thanx
Bill, who installed this for you??? I have just been reading the codes and resetting them with a OBDII scan tool, but I'd much rather have an O2 Sim installed.
Me. I had done a temp job a couple of weeks ago to see if it would do the job. I will do the permanent install this weekend.
We just did an O2 sim yesterday on a 360. The part was $35 USD and the labour was $50. Let's see if it works as advertised.
Have you reset the ECU? Cut the main power, it's on the upper left of the front when you open the hood. Then turn it back on and then start the car. Make sure everything is turned off, radio, ac, etc and just let it idle for like 5 min. I had the same setup as you and that is what turned off the CEL. I had to do it every 1K miles or so. Also make sure your gas cap is on tight.
IMO, that's not the best way to do it. Each time you turn off the power, you have to reset your radio, the ECU's need to reestablish parameters, etc... Plus, you don't know WHY the CEL went on. Instead, a much, much better way is to invest $50-100 in a scan tool that plugs in under the dash, reads the codes (so you know it's only the O2 sensor CEL), and resets the codes to turn off the CEL. Of course, the best way would be a O2 Sim.
Bill, I'd like you to do the same for my car. Was this an electronic O2 sim that you bought, or is it just a plug extension that positions the O2 sensor farther out from the pipes??? Details, please!!!
My understanding is that the CEL is a catch-all warning for a large variety of potential engine problems in addition to the CAT sensors. Both times the CEL came on in my 02 coupe it had nothing to do with the CATs. If youre going to run without CATs (and Im not sure why you would want to), perhaps you should install a simulator so you can be informed of all the other things the CEL might mean. Just a thought
Have you tried letting the o2 sensor sit out of the exhaust flow? For instance, remove it from the exhaust pipe, tie it up and plug off the hole in the exhaust. Usually the post cat 02 sensors only need to measure a difference in exhaust gas, this tricks the computer into thinking that there is a functioning cat still there.
Hello guys, i bought 360 14 days ago and i think i have same problem. My car is 01 F1 360 with TUBI exhaust and after every certain period like once per 200 km i have "Check engine" light on. I think that mentioned "CEL" light is the "Check engine" light?!I have to turn off the power (as described below by button in front trunk) and light goes off. But after some short period is going on again. Sorry for maybe stupid questions but i never owned Ferrari before. What is CAT,O2 sim,OBDII tool ? I am going this Monday to Ferrari service anyway, but good to know something......
Masar, I recommend that you stop reseting your car now and take it to someone who can read the code and tell you why the light is coming on. The reason could be serious so you should want to know, most likely the reason is not since I assume your car is running just fine. CAT is a catalytic convert O2 is oxygen sensor. SIM is an O2 simulator to fool computer that the CATs are still on. http://www.obdii.com/background.html What is OBD-II? In the US, On-Board Diagnostic systems are in most cars and light trucks on the road today. During the '70s and early 1980's manufacturers started using electronic means to control engine functions and diagnose engine problems. This was primarily to meet EPA emission standards. Through the years on-board diagnostic systems have become more sophisticated. OBD-II, a new standard introduced in the mid-'90s, provides almost complete engine control and also monitors parts of the chassis, body and accessory devices, as well as the diagnostic control network of the car.
An OBDII reader is relatively cheap and will allow you to read the check engine fault code as well as allowing you to reset it, thus turning off the CEL. Mine is an Actron PocketScan. Comes with a book listing the standard codes. The other codes have been posted here in the past, so a search will likely turn them up. I have a tubi exhaust and larini cats. In the one previous instance where my CEL would come on consistently there was indeed a problem. Had it fixed and all was good for over a year. Just last week had a new code, but that appears to be due to an aging sensor. I won't know for sure till I replace it. So my recommendation is to check that there isn't a real problem causing the fault to appear. As mentioned by someone else, faults are not limited to just catalyst issues. If you have no cats at all, then you are likely stuck having to go with the O2 simulator so that you can trust the indicator when a real problem occurs, but I have no experience with sims. Lou
Thanks for infos! I should know the reason on Monday since the Ferrari service should tell me. However if the lights goes on, there is no decreased power, etc. Car is running normally. Today i spent afternoon by driving the car and CEL did not come at all....
The OBDII gives me problem explanation only considering "Check Engine" problem or its full diagnostic device for all possible car failuires?
