Stuck, Rusty O2 Sensor - 1989 F150 4.9L

Stuck, rusty O2 sensor on a 1989 F150 4.9l. Not something I deal with very often in the south.

Heat the pipe more than the other so it will expand from the o2

Unfortunately i walked away defeated tonight,had my vehicle on jack stands so i was too scared to hammer it.Tomorrow i will try a heat gun and a WD 40 and if that doesn't work,i'm bringing the vehicle to a mechanic. Thanks for this video.

You Don't heat up sensor you heat up the NUT that it screws in to... HEAT EXPANDS,, therefor you want the NUT to expand and LET GO of the sensor,,,,

My son was doing this the other day, heated the hell out the sensor, then spayed it with PB Blaster. The BP Blaster ignited and spayed out of the tube like a torch..: with burning droplets falling on his head. Luckily, he came out of it only with some singed hair. HEAT + PETROLEUM = FIRE Wear those safety glasses folks!!

One other trick I saw was to put a hose clamp on the O2 sensor socket - keep it from spreading .

Thanks for posting this. Were you keeping most of the heat on the bung or just heating everything?

[@mangasingh8050]

Have you any clue where to ides

[@JohnSmith-cf4gn]

Mine come out easy with a 7/8 open end wrench after spraying it with stuff to loosen bolts.

Is there only one O2 sensor? I have the same year and 4.9

[@bolognablake]

Correct, there is only one.

[@robb5023]

@@bolognablake thanks. Do you by chance know what appears to be a sensor just by the fuel pressure regulator? Not the air intake temperature sensor. Between that sensor and the fuel regulator. It is less than a 1 inch from the fuel pressure regulator.

Besides the wiring issue, was there anything else going that led to believe it was a bad o2 sensor? Dealing with a hard start/throttle response issue with my 88' 4.9l

@@redjuice23 it had an O2 code
