i got my car back from the trans shop on yesterday and the oil pressure gauge wasnt working. they rebuilt the transmission, are these things related?

The oil pressure sender is pretty close to the tranny and where you have to mount the starter, so its not impossible that they could have knocked the wire off the sender.

yeah, look for the wire, it goes in the area under under the oil filter.

I believe its also either yellow or orange.

thanks guys would this be easy to do or should i gripe at them to fix it?

check it yourself, see if the wire is connected to the sender, do you know what the sender looks like?



Its under the oil filter, its a cylindrical thing sticking out the side of it, it protrudes towards the fender area, and on the end there should be a wire

attatched to it. See if the wire is there and if is if its broken, or just wiggle it back and forth a little if it is connected and see if it works.

ok cool

if you want to bring it by on thursday im off work and can take a look at it. ive even got an extra sensor now if yours is busted

thanks travis for the offer but you know its already fixed bc you fixed it. but everyone i have a new prob now, sometimes when i get on it a little the tach will drop to zero and the engine check light will come on. the car still runs, but no tach. as soon as i turn it off and back on the light goes off and the tach works again. any ideas?

If the check engine light comes on then there's something wrong and you should check the codes, unless the engine is just stalling, which would cause all of the dummy lights to come on.

next time it does that try wiggling the key a bit and see if

it changes anything, dont shut the car off, just wiggle the key a little.

the engine is not stalling. the tach just stops working and the check engine light comes on. it starts to work as soon as the car is restarted and everything else works fine when its not on. does this have anything to do with the transmission guys? it seems like it would since its the tach

Turning the key back and forth just resets everything...for a while. Check the codes:

An example of somebody who didn't:

A guy I know called me to ask about his check engine light. I told him what it probably was, but he should check the codes anyway. He didn't listen and kept driving the car. Then he blew his motor. Your motor can be good internally, but if the controls are messed up it could blow.

You should also check out the factory manual for more detailed descriptions of the error codes:

I was just mentioning the key thinking maybe he had a little electrical

bug like that vert when we first started it and nothing wanted to work.

In that cars case though it was just from sitting, dont have to wiggle the

key no more.

Also, the tach functions from a signal off of the trailing coil. I had a non-functional tach for a long time and I mentioned it to a well-known rotary mechanic out here. Just off his head, he said to run a (ground) wire from the coil's bracket to some good grounding point nearby. It fixed the problem immediately. I'm not too sure how the Check Engine Light fits into this though. It may be a completely different problem...

Yeah, but with the check engine light going on it's a good idea to check things out thoroughly.

yeah thats what the check engine light is for. i bet you get a trailing ingnition code

Egg-sactly

trailing ignition?? whats that gonna do?

its her thyroid gland Johnny, we cant find it, were going to have to do a thyroid search.

ummm

trailing ignition?? whats that gonna do? [/quote]

It controls the firing of the trailing spark plugs. If your trailing coil/ignitor isn't working properly the car will still run, but your tach may not work.

hmm so i might need a new trailing coil pack?? would this cause the idle to be reeeeaaally sucky at times and make the car die when idleing but before its in gear

it might, check the codes



mike

cool

ok this is what i got. i got 2 codes one was a long short, and the other was a short. that means that my trailing ignition coil is sending an error and my intake air thermosensor (engine) is sending an error. are these related? would the thermosensor have anything to do with my cone air filter??

ok wtb a trailing ignition coil pack??

did you test the one you have?

well the code says its bad. how do i test it?

If you dont have a manual you can look it up @ fc3s.com, it takes a while to load but me explaining it when im hammered will take much longer https://www.nopistons.com/forums/pub...IR#>/wacko.png

thanks once again 89

hey dont thank me yet, I fucked up, it's fc3s.org. sorry

actually i tried to go to fc3s.org but it was down.

try unplugging it and plugging it back in. also make sure that the ground is clean



mike

ill try that thanks a lot for all the help guys.

In my opinion it's more likely that they are fine and it's just the electrical connections... which is what the others are mostly suggestin also.



The sensors don't 'send' codes BTW, when the ECU detects a fault it's usually it detects lack of continuity on a circuit, or incorrect resistance (same thing really)



The S4 is very primitive and basically just checks for continuity on the ECU integrated engine components, but the S5 does more checking on the expected resistance ranges, and on more of the components including the emissions junk.



So it's likely you have wiring problems, faulty connections, or bad grounds... just check all that stuff out and you'll probably find a number of things.

cool thanks a lot. do you guys think i could pin this on the tranny guys?

that should work, i've seen it bolted to the trans on one of the slave cylinder bolts in a manual, i've also seen it bolted to the rear engine housing, using one of the bolts for the inspection cover up top.

ok cool ill take it up there and gripe at them, since they didnt hook my oil pressure sensor back up either
