RPM Drop Too Low During ISC Off Test (1.9L EFI)

22 Manifold Absolute Pressure/Barometric Pressure Sensor Out Of Self Test Range (i believe it doesnt have a map sensor..)

23 Throttle Position Sensor Out Of Self Test Range

39 AXOD Converter Bypass Clutch Not Applying Properly (uhh front wheel drive only?)

47 4 X 4 Switch Is Closed (its 2wd)

Have you gone through and cleaned all the wire connectors good with electrical cleaner and put back together with dielectric grease. Sand all grounds metal to metal. Look for cracked bare or broken wires and fix as necessary. Especially around the manifold/s. Allways address the lowest number first clear the memory and reset the computer by disconnecting the battery for 1/2 hour. Any time you clean or change a senser clear the memory and reset the computer to confirm the repair.
