P1153 TOYOTA Meaning

The air-fuel ratio (A/F) sensor varies its output voltage proportionally to the air-fuel ratio. Based on the output voltage, the engine control module (ECM) determines whether the air-fuel ratio is RICH or LEAN and adjusts the stoichiometric air-fuel ratio. The ECM also checks the fuel injection volume compensation value to verify whether the A/F sensor is deteriorating or not. The deterioration of the A/F sensor response is determined by the ratio between the A/F sensor output voltage change and the fuel compensation change.

P1154 Meaning

The Powertrain Control Module (PCM) continuously monitors the activity of the Heated Oxygen Sensor (HO2S) for 100 seconds. During the monitoring period, the PCM counts the number of times the HO2S responds from rich to lean and from lean to rich and adds the time it took to complete all transitions. With this information, an average time for all transitions can be determined. The PCM then divides the rich-to-lean average by the lean-to-rich average to obtain a ratio.

  • Engine Light On (or Service Engine Soon Warning Light)

P1154 BUICK Meaning

The Powertrain Control Module (PCM) continuously monitors the Heated Oxygen Sensor (HO2S) activity for 100 seconds. During the monitoring period, the PCM counts the number of times the HO2S responds from rich to lean and from lean to rich and adds the time it took to perform all transitions. With this information, an average time for all transitions can be determined. The PCM then divides the rich to lean average by the lean to rich average to obtain a ratio.
