Alright so I’ve been dealing with the limp mode on the car for awhile now so I just want to see what some more experienced people think.
Things replaced:
MAF sensor
Fuel pump
Camshaft position sensor
ABS, Traction, Red brake light and CEL are on.
No vacuum leak (did smoke test).
02 sensor thoughts? - When watching live data - I noticed that at idle the Upstream sensor bank 1 and downstream sensor bank 2 read 0.0 V at idle and then at 2500 rpm they switch and read fine but then upstream bank 2 and downstream bank 1 read at 0.0V.
Any ideas what could be the cause here? I included pics of what codes the scanner pulled up.
