17748 Camshaft/Crankshaft Position Sensors (B2) - Out of Sequence A


anyone know how i go about sorting that out!!

cheers

 

[stoneyfordNI]

did you get a timing belt fitted recntly , sounds like its out a tooth or two

 

[wazo]

either that or the iming belt has slipped a notch, have read of this before and subsequently the slipping of the belt has blown the engine up id get it checked out if i were you

 

[cupra_steve]

Ye definatly get that looked at mate ! If you have had a belt fitted it int too bad, you just have to get it refitted and the timing sorted ! Otherwise it sounds like the timing has jumped ! Possibly down to a dodgy tensioner ? or water pump pully ? either way there's nothing stopping it from jumping again !

 

[PAUL HEV]

all sorted now timing was a tooth out

thanks

 

[Forbez]

Crikes!! Lucky you caught that one before there were any problems!

I've got this fault code now, slightly different....

17748 - Camshaft Position Sensor (G40) / Engine Speed Sensor (G28): Incor. Correlation
P1340 - 35-10 - - - Intermittent

Had the cambelt and roller replaced last week and i'm thinking it hasnt been timed properly or could it be something else?

 

[PAUL HEV]

sounds like same problem,timing's out

 

[PhilW]

Yeah i think so, must be 0.5/1 tooth out as theres no problem with the cars performance/idle/running etc..

Id still take it back to where you had the timing belt fitted and get them to redo it.

It's intermitent! Clear it see if it comes back! i had that one ages ago, haven't had it since

 

[PhilW]

I cleared it last week after i had it done. I'l let the garage know, but in the meantime i'll keep and eye on it.

Where are these sensors? Any chance they are a push plug type that might have been a little lose or is it completely different?

Possible Causes
Timing Belt incorrectly installed
Camshaft Position Sensor (G40) faulty
Engine Speed Sensor (G28) faulty
[edit]

Possible Solutions
Check Timing Belt installation
Check/Replace Camshaft Position Sensor (G40)
Check/Replace Engine Speed Sensor (G28)

 

[PhilW]

Cheers tom, just confirmed what i thought.



Where are the sensors so i can rule out dodgy connections.

PhilW

Did you fix this problem....have the same situation on my S3...

 

[PhilW]

Not yet. Gonna be lookin at the timing belt tomorrow to see if its out. I'm 99% sure it is now. My rr graph suggest its pulling back at 5k which sounds about right for retarded timing out a tooth etc..


Have you just had your timing belt done?

 

[petermunns]

Ummm my car does faulter abit at 5K notice it in 3rd the most and long motor way trips... :S

Yep just had my time belt done...but they say its out by half a tooth each way...??

 

[PhilW]

Gotta be out slightly, needs to be bang on ideally. Take it back and get them to sort it.

 

[mr_D]

but i have this code and i haven't had timing belt done. This was done 10.000 miles ago. Haven't done anything to the car. Is it that easy for belt to slip?

 

[cus]

sorry to bring up an old topic, but i have had this fault on my car ages. did you lot get it fixed??
i really dont think its my timing belt, due to the fact that my car is running perfectly fine, and not pulling back at high revs. idles fine, and good MPG.

anyway, i just need to know the position of sensors G28/G40. crankshaft and engine speed sensors
