Trouble Codes

I pulled Code 28 from the CEL, and the o/d was also blinking code 16 it seemed..

here is the video of it..

According to other posts, Code 28 is the main O2 sensor. Would this explain why my heating/hvac is screwed up?

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.

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?

Would the speed sensor have anything to do with cruise control?

[Toysrme]

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

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?

[Toysrme]

Assuming the wiring is OK & it's just the sensor (That's the case the majority of the time)

You replace the sensor.
