truplaya22688 Posted August 10, 2005 Share Posted August 10, 2005 Ok, first off i tried to look for this post and couldnt find one, just letting everyone know, and if there is one im sorry for opening another one, i apologize to the pro's in the forum, my problem is that i had my car checked by a garage and my bank 1 O2 sensor is bad. As i was told this is the rear one. I just replaced the front one about 3 months ago and now the rear went. My problem is i need to know how to change the rear O2 sensor, i already have the sensor and just need to know its location and how to get to it. Its a 1996 ES300. Just hit the 125K mark, I have had it since it had 82K on it, and havent done much maintainance wise except for brakes, tires, and spark plugs. Is there anything i should be changing at the 125K mark? Also are Bosch Platinum +2 spark plugs good for this car? Sorry for all the questions, just dont want to make a stupid mistake that might end up costing me an engine. Can anyone please help? Thanks! :chairshot: Quote Link to comment Share on other sites More sharing options...
Toysrme Posted August 10, 2005 Share Posted August 10, 2005 At 125,000 miles, all o2sensors have long since been lazy & probably should have been replaced years prior to begin with, so I wouldn't complain too much. ;) I have one DOA at 107,000 miles & it's been bad for longer than that. Rear exhaust manifold, the passanger side of it. For replacing, it's the same as the front (2 bolts, pigtail connector). Good luck, it's very, very hard to wiggle down there from the top. It's a better job if you throw a towel over the engine & drop a 5 year old in the bay. If you have jackstands / ramps, there's less obsticals from under the car, but it's a little bit of a reach. Also, you don't want to try it if the car has ran any amount of time in the last two hours. The 1994 Toyota Repair Manual: You should exclusively use NGK, or Denso plugs. Other plugs will not perform correctly on Nippon-Denso style ignitions. (Like Bosch) More of the 1994 Toyota Repair Manual: It's time for a new timing belt & water pump. Anytime you change the T-Belt, might as well ditch the two drive belts. Quote Link to comment Share on other sites More sharing options...

Changed the O2 sensor and the car now gets better gas mileage and the check engine light is finally gone! Thanks Alot! Also will do with the belts and pump, just got the belts and also got the air filter and PCV valve, will get the pump in a few days. Thanks alot once again! :) Quote Link to comment Share on other sites More sharing options...
