Check engine help
Ok so I turned the key and got two codes, first was
22-
ECT sensor voltage too high or too lowEngine Coolant temperature sensor input out of normal range. Check engine temperature sensor.
I pulled it off and it was dirty, cleaned it well and left the battery off all night to reset the computer and it's still throwing the code so I am assuming I just need to replace the air intake sensor.
Second is
33-
AC clutch relay circuitShort or open in the AC clutch circuit.
I have no clue what this is or how to approach it, but I would like my check engine light off.
Any input or help would be great, maybe even possible prices if you know them.

22 - i think replace engine coolant temp (ECT) sensor, on front of intake. some of the older years have 2 sensors, one for the computer and one for the gauge. i don't think you need to change intake air temp (IAT) sensor in the top of the intake.
33 - in the power distribution center (PDC) box next to the battery, there are a number of relays. all are the same. should be a label in the underside of the lid. move something like the horn relay to the AC and see if it helps.
just for info - you can reset the computer (and clear all codes) quickly by disconnecting neg battery cable and turning on the headlights for 30 seconds. this drains the computer memory of all power.
