Good stuff. My Toyota with a 1GR-FE has 4 cats and 4 O2 sensors. Ran rough with poor fuel economy. Swapped out all 4 O2 sensors - both secondaries were outputting OV (I was fortunate enough to have access to a scan tool) - and it now purrs like a tiger cub. Just like it should.

[@easyautofix]

MARVELOUS!

[@707area]

Was your Toyota running bad before swapping the 02 sensors? I have an 05 Chevy Silverado, just swapped out the transmission and a few other parts. It ran good for a day but today it just wouldn’t give enough power, it would stay at 4k rpm at 60 mph. Had a check engine light and the only code that came up was 02 sensors. I’m wondering if replacing the sensors would fix my problem.

[@neilwisnewski7013]

@@707area Just a general feeling that it wasn't quite itself. Nothing like what you are experiencing. In all these situations, my rule is if it isn't right fix it as there is often multiple causes that combine to make all the symptoms. Hope this helps, it sounds to me like there may be other issues present. Good luck.

I don't clean mine, I replace them! And I don't follow the 100,000 miles rule. I follow my own instinct. I change mine every 45K to 60K miles depends on how I abused my work truck in a daily basis. I replace 2 of them because my work truck only have 1 catalytic converter so there's 2 of them 1 for upstream and 1 for downstream. I always putting brand new OEM Genuine parts from Nissan, oxygen sensor. After I replace them, I'm also cleaning up the throttle body, MAF Sensor too, and the Air Filter as well since I got Volant Cold air intake on my Nissan Frontier truck. And after all that I'm gonna check all the 6 Spark plugs, if they're still in good condition then I'll leave it there, but If one of them is messed up then I'll be replacing all 6 Spark plugs. So I'm all done replacing the Oxygen Sensor, also checked and or replaced sparkplugs, cleaned/inspected the Throttle body and MAF sensor, then I'll be checking the Fan Belt check/inspect and or replace If necessary. And the other components and parts like water pump, pulley, Fuel Injectors, Transmission Gear box gear oil change, Clutch, Differential Fluid Change, Radiator Coolant check or change, Radiator check/Inspection/ and or Replacement if necessary and so on and so on will be follow up in the next maintenance schedule. this is how I conduct my preventive maintenance on all of my vehicles that's why my 2010 Nissan Frontier Nismo 4.0L V6 (VQ-40) Turbocharged 6 Speed Manual transmission truck is now at 713K miles. Still going strong and still have tons of power and torque.

great , informative video , I wonder if you come across this strange problem engine 651 2.1 L (P02A7=cylinder4 fuel trim at min ) from the code you would think injector problem but sadly that was not the case , I swapped inj4 with inj1 and still the same problem P02A7 , went toward vacuum and checked all vacuum parts (intake manifold /vacuum resonator/turbo actuator/transducers/vacuum hoses) with no sign of vacuum leaks at all , in fact the system holding 15inch vacuum with no problem at a all , in regards to injectors tested with injector leak test all four injectors are leaking the same amount of fuel so I can't fault them , engine idling is fine / drive fine the only thing is if you cleared that code , you will get the full power of the engine I mean the turbo will be working as it should be until you drive in steady speed like 65miles/hour for 10 to 15 minutes as soon as you take your foot off gas pedal the check light will be trigrad and you will start loosing power specially up hill , the only suspect left for me is o2 sensor , I haven't replaced it yet , but when I disconnected no check engine light show up as if its connected , but am thinking that could be the o2 sensor is faulty thats why when the engine on that steady speed and by the time I let off the gas pedal , the ECU request the oxygen from the o2 sensor and most likely the wrong values from the o2 sensor is the suspect what do you think ? your help is appreciated
