DTC P0134 and P0154 for No Activity Detected in Oxygen Sensor Circuit

This product sheet contains explanation about oxygen sensor circuit, malfunction, induction system, bank, exhaust, stoichiometric, exhaust system, heater, vehicle, scan tool, and sensor. Lots of info related to oxygen sensor bank, sensor bank, force, heated oxygen sensor, catalytic converter, freeze frame, scan, tester, zirconia element, and tool are presented inside this product sheet.

In this product sheet we can find things like output voltage, sensor circuit, data, injector, detected bank, output, system, valve, voltage output, engine, and platinum electrode. These are selected from this product sheet:

To obtain a high purification rate for the CO, HC and NOx components of the exhaust gas, a three–way catalytic converter is used, but for the most efficient use of the three–way catalytic converter, the air–fuel ratio must be precisely controlled so that it is always close to the stoichiometric air–fuel ratio. The heated oxygen sensor (bank 1, 2 sensor 1) has the characteristic and that output voltage, which changes suddenly in the vicinity of the stoichiometric air–fuel ratio. This is used to detect the oxygen concentration in the exhaust gas and provide the ECM with feedback to control the air–fuel ratio. When the air–fuel ratio becomes LEAN, the oxygen concentration in the exhaust increases and the heated oxygen sensor informs the ECM of the LEAN condition (small electromotive force: < 0.45 V).

Additionally, this product sheet explains more around heated oxygen, oxygen, oxygen concentration, concentration, voltage, circuit, induction, electromotive force, air induction system, and oxygen sensor.
