engine light on

Asked by Jul 21, 2017 at 05:06 PM about the 2006 Dodge Ram 1500 Laramie Quad Cab SB 4WD

Question type: Maintenance & Repair

2006 1500 4x4 w/4.7   says O2 sensor bad. I had a shop replace all 4 of the O2 sensors. The light is on and still says the #1 sensor on bank one. He says the computer has to be flashed?

Other issues can cause a O2 sensor warning such as a vacuum leak or the engine running too rich or lean.

Post the actual trouble codes if you have them.
