2002 lancer es o2 sensor Heater circuit malfunction bank one sensor one
Code p0135. The thing is looks as o2 was recently replaced. I believe they changed with Universal 02. Thing I'm having trouble is wires have been cut and switched around. Coming from the car is four wires one black one white coming out as one and seems there is a bear wire also coming out going to nothing. And two single wires along side black and the other blue. Now from the top o2 also has four wires. Blue,white and two black. Which ones should be together so this code can be gone and the car can run right. Also have three other codes p0421 Warm up catalyst efficiency below threshold bank 1. P0446 evap vent control solenoid circuit malfunction. P0302 Cylinder two misfire.
