P0340 code and burnt oil smell
« on: 04 March 2010, 18:30:26 »
hi guys
just joined up as i've just bought a 1997 2.0 16v omega. have given it a good going over and sorted out a few issues. (i had a knackered alternator that played havoc with my dashboard..!!but all sorted now).
just got a couple of things that you guys might clear up for me. my EML's on and after having the codes read have got P0340 code indicating the cam sensor has a poor conection. there seems to be a bit of a bodge job done on mine with cable connectors joining the wiring to the cam sensor. I replaced the sensor and rewired the cable better but am still showing P0340 code. it seems this "spliced" cable is normal? some sort of upgrade to the sensor? the result of this fault seems to be the rev limiter cutting in at 4500, and generally poor power delivery. the other problem i have is a strong smell of burnt oil in the cabin pressumably through the air ducting. the last time i had this was on a saab and it was poor crank case breathing. is this a similar problem? any help on the above would be great.
cheers
andy

also, if someone has modded wiring, may be worth double checking its correct :)

Not owned a 2.0 myself, but I recollect various members having only sporadic success with pattern sensors

the 0340 and the 4.5k rev limit show ecu is unhappy with the signal its getting from sensor. Whether thats the wiring, sensor, or reluctor ring is impossible to say.

the replacement sensor come with a new loom which you have connected on?

You can get a sensor which fits the original loom, get Vx sensors, pattern are crap for the 4 pots.

yeah your prob right, best buy official sensor. i'll wire up the cable properly and test it again before buying the new sensor but looks like i'm gonna need it. (hope it is the sensor, not sure what the reluctor ring is?) is it part of the wiring loom?

sorry forgot to say, no i chucked the replacement cable away, complete crap..! wired up the original which i think was a GM part as the wiring was exactly the same (replacement cable had similar but different colour wires)
