2001 Ford F150 4 x 4 automatic, 5.4. Cannot get CAT monitor

This answer was rated:

2001 Ford F150 4 x 4 automatic, 5.4 . Cannot get CAT monitor to set. 4 new cats, 4 new O2 sensors, have driven 300 miles, but CAT monitor will ot set. No stored or pending codes.

Will your scan tool monitor the O2 sensor readings?

Customer: replied 1 year ago.


While idling at operating temp, are the O2 readings matching the Ford specs in the chart below?

Monitor the O2 and Heater and fuel trims to see if both sides of the engine are responding and acting almost identical.

You want a excellent 5 star answer & I would like to be rated the same for providing it. Consider I don't know your skill level & I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies. Try your best to respond with good detail so I can do the same. I normally log in at 3pm and work late. A rating is required. Your rating me, what I type. I am not an employee of this website, nor have control over the fees or the time it took to get a response. If you rate negative or not at all you still paid, but I get nothing. I want you pleased with me and my efforts, so let me know if your experience here has come up short.

Thanks Chris
