This is on the passenger side. I can not see where this part goes any help would be awesome. | | | 03-24-2007, 10:35 PM | #2 | Senior Member Join Date: Mar 2006 Location: Ft Lauderdale, Fl moving to Eastern PA in May of 2007 Posts: 326 | Quote: Originally Posted by watdawg This is on the passenger side.

You need to have the obc (upgrade I think) for the display. Search posts....I've read about someone around here doing it. __________________ '99 ti /Mtechnic, Schwartz II, Meyle Control Arms w/Full Metal Ball Joints, PowerFlex poly LCAB's, Pirelli P Zero/Nero 225/50/16, "the d-baffle"...... | | | 03-24-2007, 11:53 PM | #6 | Senior Member Join Date: Aug 2004 Location: state college, pa Posts: 3,431 | It's a temp sensor that goes in the passenger brake duct. Why do all those idiots on bf.c make random guesses? Zip-tie to anything in that area if your duct is gone (but replace the duct at some point. they're important to keeping your brakes in good shape). If you have the OBC, there is another temp sensor in the driver's duct. Why there are two, I'm not entirely sure. __________________ I scream, you scream, we all scream for ZOMBIES. | | | 03-25-2007, 12:34 AM | #7 | Senior Member Join Date: Mar 2005 Location: Portland Or Posts: 2,666 | One for OBC one for the ECU to read outside air temps to keep the motor in tune....

So the tech back then wasn't as good. Same applies to O2 sensors, never piggyback a on board display unit with your engine O2, just add a second O2. For no apparent reason last fall I fixed 3 different cars in 2 weeks that were having engine issues by removing the AFR meter from the factory O2 circuit. It was somehow loading the circuit and the O2 would read too low. Its weird that stuff comes in waves, 1 week everybody has carb problems, next week they all dump fire-bottles by accident. (Not kidding!) Darn good thing we had just bought a bunch of recharge kits....

The OBC temperature probe is in the driver's side duct and the the one for the engine is in the top of the airbox on mine ('98). They don't look anything like that at all. Look at part #@ here. It's small and pointy. | | | 03-25-2007, 07:58 PM | #15 | Senior Member Join Date: Aug 2004 Location: state college, pa Posts: 3,431 | Quote: Originally Posted by pdxmotorhead Probably because temperature sensors are notoriously finicky, and converting the analog signal so there is no crosstalk between the OBC and the ECU.

So the tech back then wasn't as good. | Good call; I was thinking that it's so simple but thinking about what kind of computer I had back then (hint: about the release of the first Pentium processor) I can see why it's easier to engineer it that way. __________________ I scream, you scream, we all scream for ZOMBIES. | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Thread Tools | | Display Modes | Linear Mode | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
