I'm hoping someone can help me with an issue that has kept my car literally out of action for close to a year.
Back in July I had my oem sensor go and it kicked a code at 85 degrees in the trans like clockwork.
I had the trans taken out of the car and shipped to a mechanic who's recommended within our local GTR community.
He diagnosed the sensor issue and said I might want to consider some upgrades and I told him to fix anything he
saw that might be wrong. After all it was out of the car and open in front of him.
All told the final bill came to 11k for the Nissan dealer to drop the trans, the dodson parts, the service of the shop to
fix the transmission and the shipping for the transmission and the final re-install of the trans at Nissan.
For the first two weeks things were fine. the trans felt very tight, the slight 2-3 grind in my shift when the trans was
cold was gone, it felt great things were working well. Then suddenly the dreaded T/M Service light came on and I was
shocked. The car limped home in gears R-1-3-5 only and the accessport showed error codes P0797/P0842.
Basically one of the new dodson sensors was showing a failure. I took it to Nissan to see if the wiring was the issue
since dodson sensors require a separate module be wired in to control the voltage. They re-wired everything and
because the code only was showing itself intermittently they kept the car for a few days and were about to give it
back and the error code came back once again. It seemed wiring was not the issue. Nissan wondered why the
faulting sensor was "stuck" at 485mv while the other sensor showed movement up and down and within tolerances.
I spoke to the mechanic who did the trans work he suggested he look at it and that i bring him the car.
It took him several weeks of trying to get the code to kick so he could datalog.
When he did he finally get some data it showed the sensor go from 485 to 40mv which kicked the code.
Long story short they decided to drop the trans (again) and replace the sensor figuring it was defective.
They get the car all back together and now there is an issue with the inline sensor apparently.
I'm wondering if any of you are or have ever had similar issues with dodson sensors or sensors in general?
I am running the required amount of DCT fluid, the Amsoil brand.
The module and wiring have been ruled out as the cause even though the times between the codes coming might
have been 20-30 starts of the car.
ANY THOUGHTS OR INPUT ON THIS WOULD BE SO GREATLY APPRECIATED AND THANK YOU FOR READING!
TAKE CARE OF YOURSELVES DURING THIS PANDEMIC AND PRACTISE SAFE DISTANCING,
