Hi I have a 2015 Lexus IS 350 f sport AWD, my warning light recently came on throwing the codes above. I have a hps cold air intake. An invidia axel back, and just recently put Bc coilovers in. I was on the throttle pretty hard when the warning light popped up. Just asking for some help or if anyone has had the same issues and how’d they go about fixing it. If all else fails I’ll just spend the $140 to get diagnosed but I wanna see if I could fix it myself first. Thank you.
Most likely due to the intake but it could be spark plugs too. I also had code 1170 on my 200T which I got after doing an injen intake.
I ran injector cleaner, put stock intake on and cleared the code and it did not come back. My car was also misfiring at the time and doing the above did not fix the misfire but swapping new spark plugs fixed it.
I attached the print out with the codes I was getting.
See i don’t know, I disconnected my battery, took out my MAF sensor cleaned it. Reconnected everything on the intake to make sure it had a tight seal. Checked all the wiring and connections an everything looks good. Start it back up and the light comes right back on. And my engine isn’t misfiring, or having a rough idle. The car is running normally or so it feels like it is. But it’s just throwing codes and i don’t even know where to look next.
How long did you leave the battery disconnected?
If you have a scan tool to check the codes, what happens when you clear them? Do they come back on right away?
Maybe the simple answer is the best answer...the MAF needs replacement. The P0101 could just be causing the other two codes.
