Hi i have just purchased a spark in UK (two weeks ago) and i am having a lot of exhaust temp sensor faults with it. This predominantly happens at cruising speed approx 35-37 mph when the ex sensor occasionally senses an over temp situation. My question is does anyone else here have same problems and any cures. Secondly do usa models have flush kit preinstalled.

i haven't read about this issue yet from other owners.

but i dont think many have gotten much use from their sparks yet.

what did the dealer say?

problems

Seadoo don't want to now to be honest. So far my dealer had to replace a crank position sensor when it failed BEFORE even going in water. Then they replaced the exhaust temp sensor after 1 hours use. 1 hour later check engine has come up AGAIN!:mad:

Wow, that sucks. Sorry this happened to you. I hope that this is a one-off problem and not indicative of the quality of all Sparks.

I haven't heard many other problems so far though. I will keep my eye out for a pattern to start developing now.

At least Seadoo is helping you out with it.

Now the water temp has risen in UK approx 9 deg c, the ski is behaving itself. I have now got it run in and thrashing it round the lake. Check eng warning has gone. So it deffo looks like the ecu update about the ex temmp sensor will be needed to stop sensor faults again when water gets cooler again in uk.

sorry folks just to reiterate the spark has a fault with the exhaust temp sensor getting to cold when running in cold water situations i.e. UK in winter lol! The ecu as factory set does not "recognise" the lower temp reading from the sensor and so displays check eng and logs a fault code with ref. ex temp out of range. There will be an ecu update to sort this out, though i think if you have a spark in warmer waters yyou won't need this update.

My 2016 Sea Doo Spark is doing the same thing only I'm in warm water. I get a check engine light after about 45 minutes but it doesn't go in limp mode. I have full speed available the error code say bad exhaust gas sensor. The dealer replaced it and reset the error code and after about 45 minutes it does the same thing. They are wanting to replace the ECU at about $1000.00. Does anyone have a clue what this could be?
