KOER Test Code 336

[Winterhawk]

My 1993 3.2 ATX has been running great all week after cleaning out the EGR passage ways behind the throttle plate. Last night and today it is getting a code 336 Exhaust pressure high and / or higher voltages than expected. I googled this and no help. Any Ideas? Auto Zone said it was a crank sensor with this code. My EZ-Read 2000 says the exhaust high and voltage high problem

Thanks

Found the problem. It was my new Auto Zone sensor. Wells SU243 DPFE.

I put the old Motorcraft DPFE sensor back in and it cleared up the codes.

MAuto Zone said it was a crank sensor with this code.

Never go back to this Autozone for advice.
