Toyota Corolla 2009 behavior after flood

#1
my '09 Corolla is not starting. I have check engine, check power steering, and low oil pressure errors displaying one after the other. Anyone with a similar experience? Please help. My mechanic removed and cleaned a sensor which looks like a camshaft position sensor and the car started. I have uploaded the sensor he claims is responsible

Partially submerged. The water level was above the tires.
same flood water level inside the interior ?
Lot's of e components up under that dash that could be creating issues.
Most notably the 'puter control syst. and electronics.

Whom serviced and dried out all the e components after the flood ?

Many people refer to repairs being done by "My Mechanic"
But unless they work solely for you... they are an independent mechanic
and tho' you may hire them for a job/repair...
They are not solely employed by you.
Unless yer really rich or something ?

How long was the car submerged in this flood water ?

In other words was it dried out properly/well prior to initial start up ?
If only one sensor was cleaned/dried... I'd hafta' think not.

Were all the fluids/oil (trans/engine/differential/radiator) changed - checked
to be sure they were not contaminated by water ?

I personnally would think more sensors then just the cam position sensor alone
could be of fault or require further drying.
Water and moisture will get into every e component below the water level.
And this can cause issue for a long time.
That is why many car are considered a total loss after being in a flood.

It's possible it fired up after one sensor was removed and dried...
so it's not likely it's not the same sensor failing again.
Unless it still has trapped moisture inside it or it's wiring.

Water/moisture will tend to ground out and cause shorts in the electrical wiring.

The Cam sensor's exterior wiring could likely be what is still shorting out from water/moisture.
Maybe not contaminated on the inside were it was mounted in the engine.
But that's not to say it didn't leak into the engine and contaminate it as well.

Vehicles surviving a flood will become challenging to get e components, wiring and sensors
dried out sufficiently and rust an corrosion can create havoc for some period afterwards.
Often causing irreparable damage in the future of that particular vehicle.

In other words... once it does dry out...
corrosion and rust can cause more issues and failures to other e components. wiring and sensors.

It's not usually just one single correction - repair.

Thanks! Just like you said, the ECM/PCM Electronics has been compromised. Have taken it to an Authorized Toyota Technician for proper diagnosis and resolution. Would update soon
