norbertk Posted February 7, 2006 Share Posted February 7, 2006 I pulled Code 28 from the CEL, and the o/d was also blinking code 16 it seemed.. here is the video of it.. http://www.flythevirtualsky.com/video.wmv According to other posts, Code 28 is the main O2 sensor. Would this explain why my heating/hvac is screwed up? Quote Link to comment Share on other sites More sharing options...
Toysrme Posted February 7, 2006 Share Posted February 7, 2006 This is the greatest "My CEL is flashing" post of all time! ROTFLMAO! Dude even took a video!!! Code 28 = o2 sensor signal on the rear (right hand) bank is incorrect over atleast 2 trips. If you download the 1993 FSM in the stickied post, you can see the trouble codes, and what to do. Go to page EG-366 You can buy generic splice in 1-wire Bosch o2 sensors for like $30-35usd. You should replace both. If you did that & reset your ECU you'd probably pick up some gas mileage. That's a code 61, not a 16. In the Automatic Transmission FSM go to page AX-83. That's the main speed sensor malfunction. It's the speed sensor, or the wiring for it.

norbertk Posted February 7, 2006 Author Share Posted February 7, 2006 Thanks for the reply.. anyway you can find the page with a diagram of where the o2 sensor is so I can replace it? Thanks.. Also the code 61, is this something serious I should have looked at? I purchased a Bosch premium oxygen sensor part 12031, anyone verify this is the correct one?

norbertk Posted February 17, 2006 Author Share Posted February 17, 2006 Would the speed sensor have anything to do with cruise control? Quote Link to comment Share on other sites More sharing options...
Toysrme Posted February 17, 2006 Share Posted February 17, 2006 Obviously. If neither the engine/transmission computer, nor the cruise control computer really know how fast the car is going - it's not going to be able to us the cruise control. Ya that's the $30 Universal one that fits. I've got 2 of them. You don't need a manual. it's on the rear exhaust manifold, passanger side. It's held on by one 12mm nut & one 12mm bolt. Unbolt it, clip it's harness off (leaving wire on it to work with), solder / crimp it on the new sensor. Installation is the reverse. AFA the PDF. Open it & hit control+shift+F Type search for oxygen sensor Quote Link to comment Share on other sites More sharing options...
norbertk Posted February 19, 2006 Author Share Posted February 19, 2006 I had my mechanic replace it for me and my heating/hvac is back to normal, except seems like 80- > HOT doesn't deliver much warmness. If I wanted to fix my speed sensor how would I go about doing that? Quote Link to comment Share on other sites More sharing options...
Toysrme Posted February 19, 2006 Share Posted February 19, 2006 Assuming the wiring is OK & it's just the sensor (That's the case the majority of the time) You replace the sensor. Quote Link to comment Share on other sites More sharing options...
