Hey Scotty & Team,
My friend has a 2016 Mustang GT 6-Speed Manual with 115,370 miles on it! So far it’s been a great car. Recently when it started raining his car occasionally started turning on it’s check engine light. It’s staying on more and more as time goes on.
After putting a scan tool on the car, he got code: P0152 which was basically telling him his O2 sensors are bad.
Is it dangerous or harmful to run the car for an extended period with the O2 sensor being faulty? (Running 1-2 months with it being broken). Also he was quoted at $450 to repair multiple O2 sensors, both paying for parts and labor. We live out in CA.
Thanks for your help as always!
Well, that code is only for one sensor, heated oxygen sensor - bank 1 sensor 2. It should not cost that much to replace one sensor and with no other codes I see no reason to replace multiple sensors.
But you should have the issue corrected because it will be harmful to the engine and affect fuel mileage. I doubt it will pass a state emission test like that. Good luck.
This sensor is only $28 from Rock Auto. Where do they get $450 for unscrewing and screwing in 2 sensors? Just get the one you need first and put it in yourself. Save yourself $420. Usually, the heating element goes bad in these.
Correcting your second code, P219B, isn't as cut and dry as the first one. It could take a little time to determine the exact cause and what, if any, parts will have to be replaced. Determining cost is speculative at this point but you probably are approaching that $450 quote unless it's something super simple like a PCV valve or incorrectly seated engine oil dipstick, tube or oil fill cap. https://www.autocodes.com/p219b_ford.html
I think (?) it will be OK if you wait a month or two before doing the repairs but I wouldn't put it off for very long. One small problem can lead to big ones as time goes on. You don't want to ruin the expensive catalytic converters, and as previously mentioned your ga$ mileage will likely suffer in the interim.
I would fix it so you won't have issues getting through state inspection.
As for how dangerous it is, it all depends on how lean/rich the car is running. I would go very easy on it until you repair the problem.
I’m sorry guys! I forgot to mention there was a second code! P219B which has to do with a fuel ratio imbalance.
So if you take that code and the original code of P0152… how dangerous is this to run as is for a month or two without changing it and what do you think a reasonable all in cost would be to correct this?
Sorry for missing that code the first time and thanks for your help! Much appreciated!
