#1875 of 1889 O2 sensor Bank 2 senor 1 removal 1997 Safari by navyblue May 28, 2009 (10:07 am)
I'm pulling code P0152 high voltage on Bank 2 sensor 1. Any ideas on what would cause that? Also how in the world would you get a 7/8 wrench in there to remove it? All books call for three sensors, 2 upstream and one downstream of the convertor but the drawing I'm looking at clearly identifies three upstream and is verified on my van? ^*$&# Any experience?

Replying to: navyblue (May 28, 2009 10:07 am) If your 97 Safari is like my 97 Astro you might want to take a look at the guide that I very recently posted on this forum with a link to some photos I took during the disassembly/reassembly process.   http://www.carspace.com/guides/   My 97 Astro has two "upstream" O2 sensors, and two "downstream" sensors. The first of the two downstream sensors is the one just before the catalytic converter. Each set of sensors has a different type of connector on it. I didn't bother trying to get to the sensors with the exhaust in place because I was replacing the cat as well. As near as I can tell, your best bet is to drop the exhaust down by removing the three bolts on each side that connect the pipes to the exhaust manifolds. You don't need to completely remove the exhaust, but just drop it down in order to access the sensors. The thing to watch out for is that one or more of the studs could break off while loosening the nuts. This is not all that uncommon. If one does break, then your in for a headache trying to remove the broken stud. Have a back-up plan ready. Plan for the worst, hope for the best. Good luck.

Replying to: Steve_01 (May 28, 2009 7:09 pm) Excellent documentation. I unbolted the exhaust at the manifold, screw jacked the tranny to hold in place, removed the "cross brace" and dropped the exhaust to get decent access to the sensor. A couple of the bolts were a little tricky but all in all, not a bad job. A whole lot of work for a two minute replacement of the actual O2 sensor. Putting it on a lift was a great help. Thank you Navy MWR! Thanks for the help. Replies to this message: Steve_01 (Jun 01, 2009 12:07 pm)

Replying to: mauialii (May 28, 2009 11:08 am) I did the same thing with Advance Auto and got a military discount on top! Life is good. I could get the socket on but couldn't get any leverage so I dropped the exhaust with little difficulty. Thanks for the tip.

Replying to: navyblue (May 28, 2009 7:31 pm) Love to hear a success story. Good for you. Nice to have access to a lift, wish I could say the same. Go Navy!
#1881 of 1889 Replace Inside Door Handle 03 Astro by rayocon Jul 01, 2009 (10:22 am)
I'm trying to replace the passenger side inside door handle on an 03 Astro. I've gotten down to the broken handle and there is a metal pin going down the center. I need to remove this pin in order to install the new handle. Problem is there are 2 pieces of metal protruding at the bottom (like a cotter pin) which prevents me from removing the pin. Anyone know how to remove this? Thanks.
#1882 of 1889 Idler pulley 95 Safari by ibridgef Sep 18, 2009 (11:54 am)
What is the easiest way to replace the idler pulley on 95 Safari? It is the pulley that is right below the alternator, and the tension pulley. Hope I'm giving the correct name. Replies to this message: Woodsmith (Sep 18, 2009 4:21 pm)
