I threw a p0150 about a month ago, I just got time to fix it this weekend. It's been on steadily since it came up the first time. It's an 09 f150 VIN 8 4.6l. 98k miles.

Which sensor should I replace? Autozone wants to sell me a Bosch 15717 downstream, but I'm not sure which plug to replace? The internet suggests the one on the driver side, but it couldn't hurt to ask you guys.


Thanks!

Take it to the dealer. I had the same problem and it was the strategy code for pcm and not the sensor.
