Ferrari Mailing List: Re: 512 TR check engine light 1-6 bank

[Doug & Terri (dnt]

Even tho your red tornado is OBD 1, having the sensor there is to collect rudimentary temp data if the cat’s too hot.  Too hot?  Sensor sends you a blinking note. 

 

Just the exhaust gas sensor on a fighter? 

 

Anyhow – what would cause an overheating cat?  The worst of the worst is a misfire.  Or a series of misfires.  Cylinder(s) is/are sending down a stoichiometric near perfect air to fuel charge which is ignited in the cat.  Not too many of those will melt the substrate like a blow torch to honey comb – then it’s the old potato in the exhaust pipe syndrome – chuf chuf uhhhhh, quit.

 

SO that said – check your ignition on the 1-6 side.  Just a guess.  Hard to diagnose a problem far away. 

 

Onward

Ok those of you who know me know that my car flies out on an initial ( no squawks)

Got a 1-6 check engine light figured it was the O2 sensor

That’s the usual suspect

Not so fast

The 512 is OBD1 so you have to do the blink code thing

Did it

Showed exhaust ECU ( there are 2 of them)

Swapped ECU’s with 7-12 bank

Cleared all faults

Cranked car expecting see fault on 7-12 bank because that’s where suspect ecu is and no fault on 1-6 bank

Now get this

Are you ready

No check engine light on either bank!

WTF?

Go drive car on a FCF run ( test drive for civilians)

Got 2 minor flashes on the 1-6 bank that self-cleared never came back on

Never seen anything like this ever.

Anyway its in the hangar bay code one

 

 

Oh yea how about the US NAVY bagging a SU-22
