oxygen sensor

Just mulling it over, over morning coffee, if my O2 sensors need to be swapped out after 298,000 miles? I don’t have codes telling me that they are bad? But do they become inefficient after so much time and mileage? Should they be changed out just for the heck of it? It came up because I did a...

I have been battling a persistent rough idle for some time and now have an O2 sensor CEL - sensor #1. I replaced the old sensors with new OEM and the code is still there. The wiring on sensor #1 is a custom job done by a PO that I can't make sense of - 6 wires in the harness instead of 4, with...

1988 FJ62, stock engine, 280k. In the last year I have replaced both O2 sensors with OEM, replaced the TPS, tested the ECU (passed), replaced the distributor (OEM), replaced plugs and wires, fuel filter, fuel pulsation damper, and more. It has had smelly exhaust for a while and nothing has...

My check engine light came on for my 1993 Landcruiser/4.5L I6 F DOHC 24V. The reader said it was both upstream oxygen sensors Toyota part # 89465-60051 and 89465-60061 ( R/L). I ordered bosh parts 13448/13081 oxygen sensors but they seemed too short. Does anyone know the best substitute ?

Hi Everyone, Need to replace both up and downstream 02 sensors on my 1996 stock land cruiser. Anyone have any thoughts, threads or comments I need to be aware of before I begin? Im handy but new to trying to fix my LC. I've purchased a 22mm offset puller and an 11inch breaker bar...

Hi fellas. Been having trouble with my '93 fzj80. Got a really strong fuel smell coming from the exhaust so I figured I'd check all of the sensors. They are all okay, except for the o2 sensor, which holds around .35 volts on the sensor wire, and doesn't fluctuate as it should. Previously I'd...

Hi there fellow mudders! For quite some time now I've been watching you from the shadow and I have finally decided to share my own Land Cruiser experience with you. As a small intro my name is Cristian I'm a 22-year-old guy that lives in Romania, eastern Europe and that's how I ended up here...

So two weeks and less than 100mi ago I ran through a 6"-8" puddle a couple times and since then my cruiser has lost power, 1st feels like 4th unless I turn on the ETC. Once the vehicle is warm it does pretty well ETC or not. I've checked the air box and it's bone dry. Next steps are to check...
