I’ve replaced bank 1-2 sensors 2 times with expensive oem. and it’s all good for a few days then it goes bad. The haltech platinum pro plugin fault code will show on the laptop.
I have a jwt tt g35. Could it be from the heat from the downpipes? What else can I try?
mice exhausted all search engines. No MAF sensor. Use only 3 bar map sensor. Replaced entire engine harness with a low mile (30k mile) o2 system from haltech. Crank sensor just replaced also. Still good until stop light then if I’m stuck in traffic. The b1 cam sensor fault will show. Car dies. In traffic. Very sad. Please help.

 

How have you determined the sensors are bad?

can you view the cam signal the ecu sees? Either from a trigger scope or even a volt meter?

 

I wish my ecu could view the signal like link and aem does. That way I could just set the window once it degrades with heat like the Supra guys do.
oil fresh. Cleaned sensor.
Im going to replace on warranty again and it’ll be good for a week or two. Then the code would start to show. Then no b1 cam signal (will show 0 degrees)
im replacing cams anyway so I’ll use this time to investigate and report back.
thanks bealjk

 

If it were me, the next time I went in there I would wrap the downpipes to out rule out the heat issue
