Engine Problem 96 PS205

Hi, I've just joined.
I have a 1996 PS 205 EFI which has a "chokey" type problem once warmed up, looking through the threads and from my own experience I reckon it may be the CTS sensor but not 100% sure.

My problem is that the boat is in France at the moment and I'm in the UK so I have to do everything remotely or collect a load of stuff together for when I go over there to try and fix it.

Does anyone know what the part number is for the CTS? Everywhere I've looked here in the UK seems to be 30-60 for the sensor (circa $50-100) to save a load of money I'd take the chance ordering from the US, where could I get it from? Any links?.

Thanks
Chris

Personally I have never seen a guage that says NORMAL on it

They usually read in degrees like 140 160 or even 180...just never have seen the word
NORMAL...just a thought

OK, I'll re-phrase! I can't remember exactly what the temp guage shows, it's just no different from what it has read for the last 10 years!

Did you check for codes? If not, do this before replacing sensors. Since you aren't there, you could have someone else do it, since it only requires a wire of some kind. This will make you "100% sure".

If it is the ECT sensor, it's usually hard to start when warm but will fire up once you open the throttle a bit, as long as the resistance is too high. Also, you may smell fuel in the exhaust, unlike a normal engine. If its resistance it too low, it won't want to start (don't pump the throttle) and it will bog when you try to accelerate.

The temp gauge won't show a bad reading if the ECT is bad- the one for the gauge is separate and has no bearing on how well/poorly the engine runs. If the ECT is bad, it's the one with one yellow wire and one black wire.

Right, dragging the thread from the depths but I've just got back from France testing the boat.

Symptoms:
Engine fine when started from cold
When coldish i.e. when the guage isn't registering it won't rev (in or out of gear) past 2600
When warm, you can barely get it over a fast idle @ 1200rpm or 20kph

For example, when coldish I had it up to 2600rpm / 40kph and tried to go faster, it either carried on the same or "choked" and bogged down.

I've changed the CTS at the rear under the manifold
The temp guage when hot is 62degC or about 145degF
I've cleaned all the earths at the front and the rear of the engine
I'm getting 5v at the MAP and TPS loom power
I've taken off the fuel pipe and blown it through (no debris of blockages)
I've taken off the fuel pump and checked for blockages (none)

It took a while to work out why the engine light wasn't coming on, MC UK put a recon engine in before we bought it and had cut the wire by the looks of it as the white connector at the back of the engine didn't have a wire coming from it (never did by the looks of it as the bungs were in both terminals) and the pink/black or pink/blue wire was just floating around the engine bay!

Anyway now the engine light works, the ECU throws up codes 22 and 33

22 - TPS too low?
33 - MAP too high?

Are these both past their best? I didn't manage to get a voltage reading from them though as I only got the engine light working 2hrs before I had to leave.

Chris
