LET Sensor help

[wiseboy]

just flashed my ecu out, its shown the following codes,

71- intake air temp (IAT) sensor - high voltage
94- camshaft position sensor (CMP) sensor - voltage high

any ideas why they shownin high voltage?

thanks Lee :thumb:

31 is the engine not running, guessing you just had the ign on, so dont worry about that.
94 isnt the sensore in the top of the dizzy? Is it pluged in, working?

[vx kev]

Other than 31 which is normal if checked when not running im not familiar with any of the others coming up on a LET unless its possbily a dizzy pack one?????

[gaznovalet]

lee let me know if my ecu is any diffrent to yours mate as cud be at fault if its taken a knock as you said, and as ben says wudnt worry about speed signal as car hasnt been driven yet, also that dizzy a gave you will hopefully sort the camshaft hall position sensor out, and for the high voltage as we said check earths and clean up the pins on the connector plugs to the afm. let me know how you get along pal.

[gaznovalet]

oh and get your mate to buy my nova now its finished

[The Simps]

31 - is that correct? I thought it was 13 for the crank sensor which you always get?

31Engine RPM signal (crankshaft sensor)No signal

Nope. 13 is o2.

55 has gone off now, 31 goes off when when engine is running as mentioned above (thanks)

bringing same codes up but 55 went off when i swapped them, still off when i changed them back ;)

[gaznovalet]

so did my ecu bring up same codes minus the actual ecu one?

[wiseboy]

yeah mate, but when a put my ecu back on the 55 code was gone

[gaznovalet]

ok maybe just been a slight dodgy connection between the loom plug and ecu pin, pleased the code has gone then for you. yous will have all the fun and games again wen your mate jonny puts my let engine into his corsa.

[wiseboy]

should be good, few people a wanna upset around hear, scooby and evos lol

[gaznovalet]

haha , dont mention scoobys!. . . . . . . they are my biggest HATE!!!
carnt stand them, my ex had one . . .enuf said lol. you will have fun killing a few along the way no worries there. thats wen you know the time and effort has all been worth the whille and is paid off wen you go past them!

[wiseboy]

still getting 71 and 94, any help??? tried changing the distributor and no change

[wiseboy]

must have bad earth somewhere, would this cause high voltage read outs?

Yes.

[wiseboy]

earths av got are,
gearbox to chassis leg,
battery to chassis,
1 behind dash
and 1 in boot.
any ideas mate?

how i could eliminate the problem?

[AlexW]

Just check the earths, make sure there clean.

And if any of the engine loom goes onto the engine make sure its clean there too (i dont know if there is as i dont do bigblocks lol)

[wiseboy]

its in getting the axhaust made up now, when i get it back and check them all
