With no engine running, you should get a 'no rpm signal' (31 iirc), so a 19 'incorrect rpm signal' does point to a fault.

Rereading post, its unclear if you are getting a 19 or a 91?

I must admit I am abit unsure with regards the coding if its code 91 it would be 91 Oxygen sensor heater Voltage high not sure what effects this will have on the rpm signal though.

Hi

With the engine running, i get no flashing at all, the light just stays on.
I will try it again though just to be sure.

If it helps at all, i went out this afternoon in it and the EML light was not on, and i could rev passed 4500 rpm, also the flat spotty pull was gone, the water tem did not go above 90°, it was like this for a 25 minute trip, i then turned the engine off, i came back ten minute laters and when i started the car the EML was back on and all the usual symptoms wre there. :-?  

The car has A/C or Climate Control?, i have the center panel with the digital read out,  a Auto and Off button, Temp + - buttons for both sides  and fan speed buttons, then the usual demist and air circulation buttons.

Sorry i for gat to mention that the car is a CD version.

Tony

Tony is there any chance you can redo the test again just to confirm the codes.

From the sounds of it you have climate control, one of the things mine is lacking  :(

It does sound like the crank sensor to me - I had similar symptoms on my old 2.0l a couple of years ago - confirmed by getting the code read.  What should have been a very straightforward job was hampered a bit by the location of the sensor and the limited access.  In the end, I removed the tensioner for the auxiliary belt to improve the access whic allowed me to replace it.  

At the time I was also advised to check the tension on the timing belt, as a difference in the signal between the crank sensor and cam sensor can also flag the 'incorrect rpm signal'.  I am sure that somebody else on here could confirm whether that is worth doing.

Hi All

Ok i just did the test again (engine not running, i get no flashes with engine running), this time i took a video of it, so i can watch it on the computer with more time. My wife and i both say that it is
*--**--*--**--*--**--*********--**  so 92  Camshaft Sensor Incorrect signal.
|-----diag start-----|  |--fault code---|

But once i have made the video smaller, if i post a link to it would you guys be able to check it for me.

The vid should be up sometime this afternoon.

Thanks

Tony

camshaft fits in with my early gut feeling, as posted earlier...

was that the only code?

cam sensor failure puts car in 'limp home' and hence rev limits to about 4k

Hi All

So i have upload the video to Goole.

Video 1 is a 1 minute video with the engine running, as you can see there are no flashes with the engine running.

Video 2 is a 7 minute video with the engine not running, i left the camera going for so long, as i have no clue how long it takes to get the codes out.

If any of you guys could take a look at the video, and comfirm my findings, that it is Code 92, that would be great.

Thanks for your time on this matter.

Cheers

Tony
