    Just finishing installing a Tubi on my car and noticed a wire had fallen off this sensor. It looks to be something that may have been added when the car was converted to US spec. (Euro car) the wire looks to have been broken for some time, car still runs perfect with no CEL on. Any thoughts?

    Looks like the Redneck temperature sensor modification. Mine is a 99' 360 and I can comfortably say.. no mod like that on mine.. I'll recheck tonight.

    BTW.. half @$$ work like that on these cars annoys me..

    Yeah it's strange, it's just mounted on that bracket, it does not go into anything else? Not sure if its some kind of knock sensor or what? I'm guessing the company that did the US conversion may have had to add it for some reason. They also added an AIR pump and wiring for it but somebody has completely unhooked it and capped off all the fittings on the manifolds. Somehow the car has no CEL, I wonder if when they added the emission stuff they made it operate independant of the ECU and that is why no CEL is on?

    That looks like it originated from some kind of 1940's truck!

    The ECU for a euro has a slightly different program but not so much that it makes a difference. To make US spec they had to add an air pump. They were technically supposed to reflash the ECU but most importers didn't do that.

    I have a euro, 99 and this is what it looks like on the drivers side:

    Trace it and rip that **** out! Dum dum mechanics that should be working on the car. Could be a temp sensor for the air pump.. Trace it, find out where it goes and get rid of it when it goes nowhere.

    Those 3 nuts on either side just hold on a plate tht let's you check camshaft timing.

    thanks for the pic, I plan to do just that, trace everything back and remove all the crap that's not even hooked up anymore. I'm thinking that this AIR pump may be a stand alone system they put on.

    If they didn't reflash the ecu, what controlled the air pump? I've changed a couple from federal spec to euro (totaly different EVAP, map etc) so interested to learn the alterations needed to make it federal spec....

    Either a timer or a temp sensor. They are not tied into Motronic, they just make sure it gets cut off prior to the O2's come on line.


    Motronic programming is very different US to base version. For one thing the sensitivity of monitored components to set a CEL is very different. Also air pump is fired off occasionally to test downstream 02's on US cars. Evap is tested on a regular cycle for leakage.


    The quality of work shown in photos is very standard. The mods are just good enough quality to make it through the test.

    SoI'm presuming they would change the headers on a 99' to 2000 and later to allow for the air pump injection? Or would they use a sample port on the cat?

    Interesting with the triggers for CEL. I also wonder if the pressure sensors on the tanks were strictly 2000 and later US model as mine thankfully does not have them. Also explains the different roll over valves between euro and US models.

    Thank you Mr. Crall!

    Well I removed it all this AM, here is what came out. It was a stand alone system, one wire (i assume it was a trigger or power wire) went over to the connector shown. When someone blocked off the AIR I don't know why they didnt take another 15mins and just remove it completely!

    Where did they have the line from the airpump going? To the headers?

    The small vac line was run over to a T near the F1 pump that goes into the vac can. The other hoses were already cut and removed prior to my starting this project. Here is a pic of the label they attached:

    That's hilarious! So it had the components for about 2 months... to get it through then were "deleted".

    Nice. Simplify things.

    Thanks Brian. Interesting info, aside from a couple of imported 360's and a few Federal cars in Dubai, i haven't come across this spec. Euro-spec cars from 2002-early2005 ran evap leakage every third cycle. Test were pressurised. Pre-2002 were vaccuum every third cycle. The carbon canister, one-way valves and purge lines are both of different diameter and routing.
