P2187 Code: System too Lean at Idle (Bank 1)
P2187 Code: System too Lean at Idle (Bank 1)Note that there is only one bank if your car has a straight engine and the scan tool will always refer to that bank as “Bank 1.” P2187 code indicates that your vehicle’s computer detected a potential issue with the fuel mixture at idle.
P2270 Code: O2 Sensor Signal Biased / Stuck Lean (Bank 1, Sensor 2)
P2270 Code: O2 Sensor Signal Biased / Stuck Lean (Bank 1, Sensor 2)Bank 1 is where the #1 spark plug is. O2 sensor 1/1 is the upstream sensor on Bank 1 (different for a Ford than for a Chevy or a Dodge), and O2 sensor 1/2 is the downstream sensor on Bank 1. O2 2/1 is upstream on Bank 2 and O2

P0141 Code: Oxygen Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)With that in mind, it’s important to note that Bank 1 is always where the number 1 cylinder is located. Thus, on Ford pickups, Bank 1 is the passenger side bank, but on Chevy and Dodge pickups, Bank 1 is the driver side bank. You need to know this, or

P0042 Code: HO2S Heater Control Circuit Bank 1 Sensor 3Bank 1 is the side of the engine where the #1 cylinder is located. P0042 code is set when your car’s PCM determines a potential problem with the heater element circuit of the oxygen sensor.
P0135 Code: Heated O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
P0135 Code: Heated O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)Diagnostic trouble code (DTC) P0135 stands for “Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1).” It is set when the car’s primary computer—also called the powertrain control module or PCM—determines that the heated oxygen sensor (HO2S) 1 heater current is higher or lower than the ideal amp for
