P0155 OBDII code refers to HO2S heater circuit - bank 2 sensor 1 , not knowing your engine size and engine vin code thats about as far as we can go with our answer . we can say bank 2 sensor 1 is the passenger side upstream oxygen sensor has a heater circuit problem , could possibly be a bad oxygen sensor . you ask what is that - thats what it is ... cheers .

For the P0155 code, check the fuse for the O2 heater circuit.
The P1494 has to do with the EVAP leak detection pump pressure switch. Or the switch is faulty, or there is a large leak. Do you hear any hissing sounds under the jeep?

Hi there:DTC P0155 - 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)
This code refers to the front oxygen sensor on Bank 2. The heated circuit in the oxygen sensor decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0155.
A code P0155 may mean that one or more of the following has happened:

  • O2 Heater element resistance is high
  • Internal short or open in the heater element
  • O2 heater circuit wiring high resistance
  • open or short to ground in the wiring harness

Possible Solutions
  • Repair short or open or high resistance in wiring harness or harness connectors
  • Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
