p0335 p0340 2005 evo 8
2005 evo 8. once in a while, only at night it seems my evo will misfire then stall out. the three times its happened to me it was at a downshift and it was damp outside too. i pull both the p0335 and p0340 codes. i clear the codes, wait 20 minutes and the car starts up acting normal. it seems to go a couple weeks with daily drivingthen does it again. i looked at the cams and it looks like one may have moved (adjustable hks cam gears) but i dont know if they advanced anything while tuning. im kind of at a loss. it runs really good and doesnt seem to have any issues until this happens. my battery is good. brand new ets mini battery. any help is appreciated.

I was getting the same fault P0340. I would get it every time I would wash my Evo 9.
Just last week, I would get it and I wouldn’t be able to start my car after a drive cycle.
Replaced the Exhaust Cam sensor (150K Miles original sensor) and no longer get the fault.
I hear due to the heat, the sensor goes bad. I opened the old sensor and found corrosion in the small circuit board, water intrusion. Very easy to take apart, no seal/gasket between the housing and circuit board. I will apply a light coat of rtv around the seams of my cam shaft sensors.

I never updated this but I got mine to run perfectly again! I think i got those codes in the first place because my car shut off 3-4 times in a row and i had to quickly turn it back on each time, as I was in traffic. So i guess the constant dying tripped my car out. I changed out the cam sensor and it did nothing. I put in a new idle air control valve, and my evo has been problem free since! Definitely try it

the exhaust one. And it stalled out again. Cleared codes, waited 20 minutes then it fired up like nothing happened. I'm going to clean the old sensor and swap it with the intake one. From my understanding they are the same. But i hit a little puddle just before it stalled out.

ill keep eveyone posted for sure. I saw those pictures. When I switch out the intake sensor I'm going to take that one apart and see if theres anything going on internally. Other than that, should there be oil in the housing that the exhaust sensor goes in to? I've heard mixed things about it.
