Hi. I am new to the chat but I hope someone can help me or direct me to where I can find help. I have a 92 348 ts and ever since I have owned it - about 20 months the 5-8 light has been going on intermitently. Sometimes the engine is cold sometimes hot. Sometimes it stays on for a week and sometimes 15 sec. There is no rhyme or reason it just happens. I have never had a bank shut down and the performance has remained steady and true. The light has now been on for a month and it won't go off. I have switched the ECU's. No luck. Any advice or easy fixes. Thanks so much.
Starting with the 348, Ferraris became overly-sensitive beasts. That means you blink your eyes wrong, you'll get a check engine light. You can either fuss with this until you're so frustrated that your car is up for sale, or accept it as a later-model Ferrari evil and go on down the road. The best fix I know is a 2-inch strip of electrical tape to go over BOTH of the "Check Engine" lights. It matches the interior black very well, and you'll never be bothered again. The only true "Check engine" gauges on your car are oil and water temp, and oil pressure. Any of these go haywire on you, you might have a reason to open the decklid. Happy driving.
The above is bad advise. Read your codes on the ECUs first. Right down the nos. that show up and get back to us here and we can go from there. Regards, Vern
Could be emissions related.. o2 sensors etc etc. These are finicky cars, how do I know ? I dont even own one yet, but I want one.. go figure.
Hey Larry, go here for Ernie's great write-up on how to see your code numbers for your check engine lights: http://webpages.charter.net/aircover/348/1994Ferrari348Spider.html#ECUcodes Once you get your codes, then compare them to this list so that you know the problem(s) that your system has detected: Ferrari 348 A/F ECU Codes (check with engine running): http://webpages.charter.net/aircover/348/1994Ferrari348Spider.html Hot wire air flow meter 1111 Engine coolant temp sensor 1112 Throttle potentiometer 1113 Lambda sensor (O2 Sensor typically unplugged or bad ground or bad sensor) 1114 RPM sensor 1121 (this code will be shown when your engine is off) Battery voltage 1122 Secondary air solenoid valve 1123 Purge valve 1124 (the purge valves are marked as part #21 in this diagram) Lambda regulation Additive value for self adaptation (O2 sensor or coolant temperature sensor or MAF) 1211 Lambda regulation multiplicative value for self adaptation 1212 Lambda regulation intake manifold compensation (MAF or O2?) 1212 *Lambda codes 1211 and 1212 refer to the fact that the emissions O2 sensors are going full tilt to regulate fuel mixture and it's still not enough. I would unplug them and run the car to add to the data base. If the car then runs normally then something in the O2 system needs to be considered. If on the other hand if it persists we can consider the code a sympathetic action. It could also be a problem with the coolant temp sensors. Way too many times I have seen a broken wire at that connector cause similar symptoms and it would also cause a Lambda regulation code. An open connection or high resistance at the coolant temp sensor will make the A/F mixture very rich. Something it can tolerate when cold but less so when you get some temperature in the motor. *thanks, rifledriver Short circuit on idle regulator 1311 Open circuit on idle regulator 1312 Electronic control unit 1313 Injection valve 1 1411 Injection valve 4 1412 Injection valve 2 1413 Injection valve 3 1414 Malfunction Indicator Lights (MIL) 1444 *dash light burned out Valve 4111 Stroke sensor 4112 Power module not used 4113 TDC control unit recognition 4114 Catalyzer temp ECU 4121 Catalyzer temp too high 4122 Speedometer signal 4123 Compressor connection signal 4131 No error detected 4444
You want a break........have a Kit-Kat Dont give crap advice like that,as some people follow the advice on here religiously,and the crap advice that is sometimes offered/mentioned on here can cause owners more harm than good. But i have feeling that you were joking....
Pap, as funny as it might sound, I'm actually serious. I spent close to $2K over the course of my first year of driving a 348 trying to chase down "check engine" light causes - Ox. sensors, ECUs, etc., etc., all the while the car ran perfectly. My mechanic told me one day that I was going to make myself crazy. So for the NEXT year, I put a piece of electrical tape over the darn lights and enjoyed my Ferrari experience much more. They still have Kit-Kats? I used to love those things
$2K? Maybe you should have tried another mechanic? I can understand what you are saying,and it would be a big headache trying to chase a gremlin that comes and goes. But,it only would come on for a reason..Whether a major issue,or a wiring short/fault. I have seen and heard crap that people do with check engine/service lights ect.....People remove the light bulbs from the dash,cut the wiring to it,paint over the light,behind the plastic facia cover ect.... Crazy! And yes,we still have Kit-Kats here
Euro cars didn't even have the CEL's connected from new. Why? I can only think it is because they didn't have to (unlike the US where it was mandatory). Why have customers coming back under warranty eating into profits when you can just not wire the bulbs in the first place..
They were put there so the normal Joe could self diagnose his car. One of the few times our government did something right to help the consumer not big business. Don't use tape to cover up the problem. I don't care what anyone says it is easy to read the codes and find your problem. It's like having your ECUs do half the work for you by tracking down the problem. Some Ferraris are known to have ground problems. If your code reads an 02 sensor there is a good possibility that it is a ground problem. Anyway read the codes and go from there. Regards, Vern
I agree Vern, my tone may have been misunderstood. I'd rather have the lights - just pointing out that IMO Ferrari was a bit cheeky leaving them out on the Euro cars. The idea is that you are warned if you have a potentially environment/cat damaging problem, unless a Euro car was running rough you would never know.
Chris I didn't take it wrong, no harm. Yea that is the problem as I see it too, you are able to see a problem before it becomes catistrophic(sp). They leave them off so you are forced to take it to them to fix it which is BS. They even make it hard for the independant to help you when things go sideways. BMW is even worse about this stuff. I'm happy that our EPA/DOT listened to whoever about this monopoly concept brewing and nixed it. Regards, Vern
