Hi,

short story,
I was driving at 40 -30 mph on a dark street and rammed through a bit of water ( maybe 4" high and 6 feet across). So right after i got these tranny codes and my tranny went to safe mode kicking hard when shifting:

P0705
Transmission Range Sensor Out Of Self Test Range Or Shorted To Ground

P1783
Transmission Over Temperature Condition

P0712
Transmission Fluid Temperature Sensor Circuit Input Low

P1702
Transmission Concern



Luckily I was a block away from home. So i assumed all those sensors shorted with water ( I thought they were all water proof...hmm) so i let them dry.

So the codes went away and the truck seamed fine for 2 weeks until i felt the tranny kicking again into gears yesterday. So today i went on a test drive and it was fine at first until it went into safe mode again with only 2 codes:

P0705
Transmission Range Sensor Out Of Self Test Range Or Shorted To Ground

P1702
Transmission Concern

So, that means the other sensors dried out and i destroyed the TRS? and if so would it malfunctioning cause the tranny to go into safe mode or could there be some other issue?


Thanx

That sounds about right. Going to 40mph through 4" of water tends to have that effect. Not knowing anything about what kind of truck you have doesnt help us either :/. Change out the sensor and reset codes so you dont destroy ur tranny.

 

Sorry, f150 2002 5.4 4x2,

Thats actually very normal around here, Water si always pooled everywhere on every road and nothing had ever happened to me on other trucks... besides that my trucks lifted. and it was a dark road...

whres the trs located?

thanx

 

The TRS is on the driver's side of the transmission where the shift cable attaches. It's the part with the wiring harness attached.

Water can get trapped in the connector, and can also get into the TRS.

 

Being a lifted truck might have even worked against you? Water splashed up travels in a trajectory. A lower vehicle's fenders and chassis will curb that trajectory closer to ground, while lifted will let it continue further.

Ummmmm, the TRS, the water, the road, ..... they didn't know it was dark.

 

haha

I read those things were supposed to be water proof, its bigger than the tps, im gonna remove it, is there any special procedure to instal he new one?

 

Yes there is. Have the wheels blocked and the parking brake set. Put the trans in N. Remove the old one and install the new one. There is a line on the inner rotating part that aligns with the outer part when the trans is in N. Line them up and tighten the bolts.

 

Ok cleaned everything and it worked, aparently the connector was soaked in water... I guess i got lucky...

thanx
