Deep Fording Cancels Ck Pos Sensor Signal?

96 1.6 16v: Anyone have real world experience w/ a stall fording rivers?

Cant say I have, how far in did you go?

I went to underneath the headlights, and it stayed running just fine.

Fan, alt, and w/p belt were screaming though, but it held...

I bent two rods fording a river . If the crank position signal is causing problems then it is most likely a bad connection. I have disconnected all of my electrical connectors, cleaned them and packed them with petroleum jelly. I use the OE plug leads (newish) and my Vit will still run with the engine underwater (I have a snorkel now).

Thanks for replies. Before the next trip I wtd to gain some insight on depth others have reached. Rubber timing cover seal may keep the worst of the water out but if you stop long enough and water reaches the space betw. the trigger wheel and the sensor it seems to me it will interrupt the signal. Better to keep moving. Will put in some dielectric grease in the connector, though-hadn't thought of that. Thanks, Rinoman.

I went through a very low ford. ie the water was low but the muffler was causing some steam so it got wet and the engine warning light came on presumably from spray going into something. 10 kilometres later I turned the engine off then back on and it had cancelled. Is this what you are referring to? The grease is a good idea I hadn't thought of that. I used to use an aviation grease on planes to stop water getting in but I can't remember what it is called.

you have an obd2 car and it will be unhappy with wet wires at crank pos. sensor on the bottom and the oxygen sensors.
just ignore the P04xx errors but losing the crank pos. sensor is going to be a problem.
so seal the connector.!

100 ways to do that,
home brew thru professional.

you could just back it in silcone grease, then warp it in plastic wrap , layered with RTV.

they also sell a tape called latex rubber uncured tape, (3m?)
it is black and gushy soft, when you wrap the tape to the splice it melts into itself.
and then cures, Inside is packed in RTV by you.

this was used for 30 years before 3M started making submirsable splice kits.
(looks like tiny coffin with jello in side) used for burying cables,etc.

there are also professional Automotive connectors that seal 100% , but
are very hard to put on , with out expensive tools. but is possible.
Look at any new chevy, pop hood and look. Delphi does a geat job today.
cheers.

thanks for that. Is the crank pos sensor inside the cover or outside?

Outside, beneath cover at base of oil pump.

crank position sensor.
that connector , must be clean.
conn. gasket good and coated with silicon grease.

if you get it water tight, it will not fail.

it can be hard to do so.
