HINT:
- DTCs P2195-19, P2195-24, P2196-18 and P2196-23 indicate malfunctions related to the bank 1 air fuel ratio sensor circuit.
- DTCs P2197-19, P2197-24, P2198-18 and P2198-23 indicate malfunctions related to the bank 2 air fuel ratio sensor circuit.
- When any of these DTCs are stored, check the air fuel ratio sensor voltage output by entering the following menus on the GTS: Powertrain / Engine / Data List / A/F (O2) Sensor Voltage B1S1 or A/F (O2) Sensor Voltage B2S1.
- Short-term fuel trim values can also be read using the GTS.
- The ECM regulates the voltages at the A1A+, A2A+, A1A- and A2A- terminals of the ECM to a constant level. Therefore, the air fuel ratio sensor output voltage cannot be confirmed without using the GTS.
- If an air fuel ratio sensor malfunction is detected, the ECM will store a DTC.
