    2006 GTX Turns Over, CPS Sensor Code

    Good morning greenhulk! Big user of seadoo forum but it doesn't seem to be quite as lively as it once was. I own a 06 RXT and 07 RXP, both great skiis. I am working on my neighbors 06 GTX and am in need of some help!

    Little bit of backstory but Ill try to keep it brief. Ski went 3 years without running. Previous owner parked it after it wouldn't run after an oil change. Cluster was waterlogged and completely dead. Threw in a new battery. Ski turns over without issue but I don't get spark or fuel. Tested both with my candoo pro and was able to manually check each coil and injector and everything seems to work as it should. Was told that it might be a CPS that was keeping the ski from starting and wasn't the dead cluster. Tested the old CPS and saw 927ohms of resistance, well outside of the expected 190-290 per the manual. Replaced the CPS with an OEM from the dealer. 900ohms resistance and seeing .7vac during crank, below the expected 1-2 vac. Old sensor did have a few metal shavings on it. Next step was to replace the cluster since this is the first year they were required to be married, we figure because that handshake wasn't happening, that was keeping the computer from firing. Bought a brand new flashed correctly cluster. Married it. No more long beep, no more error code. After this was done we imminently got a P0337 code. Strange. This is where I am today and am in need of next steps.

    Sensor is brand new. Not getting the expected resistance from the sensor or voltage output to the computer. Get no RPM shown on candoo or cluster during cranking. Not sure of next steps. I have read a number of things. Timing is off, timing chain, trigger wheel teeth, ECM...etc.

    Just not sure where to look next. I still believe I am having a sensor issue and computer and wiring is fine. Going to do a couple of things. Going to pull the valve cover off and check the timing chain and take a look at the oil filter for sparkles. Assuming both of those things look normal, can I check timing by bringing #1 to TDP and making sure the cam pulley marks are level with the head? Any thoughts would be most appreciated. Thanks!

    Ecu is my guess,try the one off the 06 rxt on the gtx if they are both 215.Them 664946 ecu are junk,replaced a pile of them in the last couple years.

    Unfortunately the RXT is a 215 and the GTX is a NA 155. Not sure that is going to work and would I have to also move over the cluster from the RXT as well? ECU issue huh? Does that make sense given that the CPS is only showing .7VAC during cranking? Is that to be expected? What would the cost of a new ECU cost? Sorry for all the questions, just trying to get as much information as possible!

    No fuel pump,or fire would lead me to believe that ecu has no out put to those.seems to be the norm for bad ecu.Try the na one,if the the pump runs and you roll it and get fire you will know.

    So fuel pump works fine when you insert the key. Both ignition (each coil) and injectors have all been tested manually using my candoo. I know that the computer can energize them without issue. My thought is the ECU is not seeing that the engine is rotating during cranking because of the CPS issue and not firing the injectors or plugs. That also explains why I have no RPMS being shown on my candoo or cluster during cranking.

    Alright, for those keeping score, I have some numbers to compare to. I just did both the resistance and VAC under cranking test with my 06 RXT CPS and here is what I got. same ~900ohm resistance. This tells me the part has been updated since the repair manual was written or its just plain wrong. More interesting I got 2.7 VAC during cranking, that's 2v more than what I am seeing on the damaged ski. At this point, I think its really only one of two things. Its either the second (brand new) CPS sensor is bad or installed incorrectly OR the trigger wheel in the PTO housing is damaged and not giving the CPS the correct data to be picked up. Going to order yet another CPS sensor and try this again...

    An update for the one person watching this thread. Got my hands on the ski yesterday. Pulled the valve cover. Everything looks as clean as it should and the timing chain was taught and tensioner looked perfect. Also pulled the oil filter and it looked clean as well. Was trying to try another CPS (aftermarket) sensor but what was ordered was a three wire and I needed a two wire sensor. So wasn't able to test that today.
