My 96 2 door cherokee won't pass emissions cause of "barometric circuit high input" and "engine coolant temp circuit low input" and also saying "coolant temp circuit high input". Anyone know how I could get this fixed? Thanks

 

Have you had the vehicle scanned for any tripped codes?

barometric circuit high input deals with the MAP sensor and it's circuit.

engine coolant temp circuit low/high input deals with the CTS sensor and it's circuit.

 

No I haven't had it. So mostly it's the circuit then

 

Find one of the shady repair shops that can do state smog testing.Pay them 50 to 100 bucks and they will say it passed.

 

Could be either the sensor or the circuit. CTS is inexpensive. MAP is. Both can be tested. Search for how to test them.

that doesnt work with OBD2 cars. they have to plug it in and if it has a MIL, theres nothing they can do to say it passed.


OP, the sheet says you have 8 codes, and lists 6. go to an auto parts store, theyll scan it for free and print the codes. post them all up. looks like you need o2 sensors as well.
