You don't have a knock sensor.

Let me rummage through the Ranger manuals for those codes...hang on a sec.

Code 335..."EGR (DPFE) sensor circuit out of range"

Code 326? Nothing in the Ranger manual about that.

In the Haynes Automotive Emissions Codes Manual, code 326 for 91-on "EGR circuit voltage lower than expected (PFE)"

Well, now we're cooking. Find you a Haynes for your rig and find the values needed to detemine if the DPFE sensor and EGR are good after testing.
