that means you need to replace the sensor,, please someone correct me if i'm wrong but i think it's behing the alternator, head down to bursons and ask for one and it should just be a screw in and plug in job, plus removing the alternator which is 2 bolts and a few power lugs, hpe it all works out for ya mate

MAP sensor is the black rectangular box bolted to the firewall. Stand at the front of the car with the bonnet open, look down the length of the big black plastic intake pipe on the passengers side, you'll see a black rectangle at the other end of it (not attached to it). The box should have one electrical connector, and one hose (running to the throttle body).

Hope your daughter comes good soon.

sorry yes i know what a map sensor is, i just wanted to know if this was a common proabalem and is there a cheap fix for the next 24 hours, turns out my daughter had to stay in hospital over night, im on my way back up there now, just hard to drive with a dead map sensor, and yes i reset the ecu every time i park the car

cheers

I don't think there's any easy way to fix it other than replacing it. If you've got a wreckers near by you should be able to just get a second hand one from there. Takes bugger all to swap it over.

As for being a common problem, I can't say that I hear of it all that often, but then again, I'm not a mechanic either.

ive seen it a bit.
as for it not working it will make the car run extreemly rich as it will think its at open throttle all the time so fuel consumption will hit the roof.
theres no quick fix for this so you can just replace it but id recomed replacing the vacume hose off the map sensor to the intalk as well as they perrish and split.
Also ckeck all other vacume hoses as well. because they can split and perrish aswell

ok guys i brought my daughter home from hospital car went ok.. but then i had to go get my other daughter and the car broke down but wont start anymore, well it starts coughs and farts for a few seconds then stalls, i changed map sensor made no differnce, i really need my car as my daughter has to go back to hospital at 7 in the morning to see the doc

Bro i'll drive your daughters around for ya!

[Jaym]

shut up idot,

Could my problem be my coil packs?

nasty........

nasty........

you deserved it...

ok do another self diag,
theres 3 things that usually go at this age that cause the same issue

1. DFI moduel (under coils on the coil pack unit)
2. CSA (crank angle sensor)
3. ECU

i had a faulty ECU that told me my CSA was dead, then told me my o2 sensor was rooted... turned out the CSA was fine, and same with the o2 sensor.. DFI moduel and ECU went..

i know this may sound silly man, but check all the ignition leads... when it coughs and splatters its not getting enough spark to detonate the fuel properly and equally, one might be loose and the spark plug might only be getting %50 spark, other than that sounds like a coil pack issue maybe you blew a coil, easiest way is to borrow a mates coil packs to find out... sucks you need the car operation and need it now...


do more testing...
and we'll try to help, hope your daughter gets better man

dont you mean cas???

Could also be the fuel pump playing up now...it can cough and splutter because it's not got enough fuel pressure to run.

When my pump died, it would only JUST idle, but only for a few second before it died.

Check your fuel filter, and pump.
