Engine Sensors and Wading

Dear All,

How do Jimny engine sensors fare when wading?

What do you all normally do to protect them?

I'm not planing on doing any deep wading as I don't plan to get water in the cab - I don't want to remove my carpets! Just need to know in case it happens unplanned if you know what i mean!

The sensors do have a reputation for failing but this seems to be heat orientated, not water. The systems are poor running/misfiring after warming up which can be "cured" by putting cool water on the cam sensor. The only fix is then to replace it.

Thanks for that Martin,

So is it that the Cam sensor is the most troublesome then?

How do you find the coil packs? - I don't mean where are they but how reliable are they?

Does the vehicle have a crank sensor?, I guess it does and if so is this not more vulnerable to water when wading due to it being lower down, i'm guessing it is not troublesome as you've not mentioned it.

I have only just bought my twin cam engine 2000 "X" reg jimny and have not had time to get under the bonnet and have a good look around yet!

I have a CD service manual from ebay but again have not had time to study it.

I like to know my vehicle's inside out as much as possible to give me the best chance of fixing them myself and if necessary out in the field.

Also, I am under the belief from KAP and by looking at tghe engine that it has a timing chain rather than a belt - is this concurrent with your knowledge of this age non VVT twin cam 16V engine?

Sorry for the million Q's

The engine has both Cam and Crank sensors. As I said, I have never heard of them being vulnerable to water and the one that people mention failing is the Cam one, due to heat.

And I have not heard of coil pack problems either.

after a good steam clean, clean up any suspect contacts, re-assemble then empty a load of sprayable lithium grease over them it repels the water and stops mud & dust sticking. You have to re-apply it when you wash it off but has worked wonders for me

Cheers for that, I've been steering clear of water for the time being as I'm yet to fit axle breathers, although thast might be sorted in the next week or month. It's only a small job I know, but one that is always having items added above it on the TO DO list!!!

We go away to the Lakes in April / May so I'll get some sprayable Lithium Grease before then. I don't think I'll be steam cleaning the engine though as I've heard horror stories about what that can do to electrical components.

Cheers again.

Oh, I forgot to ask, how do the door seals stand up to water above the bottom of the doors, do they let much in?

Crickey, sounds liek they work well then!!!

I've got an RYA Powerboat certificate from when I was Lifeboat Crew but none of the Lifeboats I drove had wheels and none of them were used on Pay and Play sites or crossing Rivers!!!

Sounds like it could get a little disconcerting but shows how tough our little Jimny's are though, even if they are a little light!!!

My Husband took my first jimny swimming on a treck along the "foss way".
He has an RYA Powerboat cert too and says its needed !!.

he did a river crossing, and the rear just floated, no water came in. the weight of the engine, and keeping the vehicle in 4wd and the wheels turning enabled the Jimny to scrabble its way out.

Next time though, it might be an idea to attach a line on the rear to stop it from floating off!.

We didnt have any problems with any engine sensors but this time, my husband is going to get some outboard grease and make sure all the electrics are fully coated just incase.
