Code P1135 Toyota: A Case Study
November 10, 2020
Code P1135 Toyota: A Case StudyAlright, that’s great. But what is air-fuel ratio sensor 1, and what is bank 1? Let me explain. An air-fuel ratio sensor (also called a wideband oxygen sensor) is an advanced type of oxygen (O2) sensor. Like a traditional O2 sensor, an air-fuel (A/F) ratio sensor measures the amount
P013E Code: O2 Sensor Delayed Response – Rich to Lean (Bank 1 Sensor 2)
November 10, 2020
P013E Code: O2 Sensor Delayed Response – Rich to Lean (Bank 1 Sensor 2)The purpose of the downstream oxygen sensor is to monitor the amount of oxygen in the exhaust. The PCM uses the data the sensor provides to determine the efficiency of the catalytic converter. The module monitors the signal coming from the oxygen sensor, checking how long it took for the
P013C Code: O2 Sensor Slow Response – Rich to Lean (Bank 2 Sensor 2)
November 10, 2020
P013C Code: O2 Sensor Slow Response – Rich to Lean (Bank 2 Sensor 2)The downstream oxygen sensor is used to monitor the efficiency of the catalytic converter. It also measures the amount of oxygen present in the exhaust. An exhaust stream that is in lean condition has more oxygen present in it, which prompts the oxygen sensor to send a low signal. However,
P013B Code: O2 Sensor Slow Response – Lean to Rich (Bank 1 Sensor 2)
November 10, 2020
P013B Code: O2 Sensor Slow Response – Lean to Rich (Bank 1 Sensor 2)Oxygen (O2) sensors keep track of the oxygen levels in the air that enters and exits the catalytic converter. These sensors send data to the PCM, which will be used for post-catalyst monitoring and fuel control. Each oxygen sensor compares the oxygen content of ambient air with the oxygen content
P013A Code: O2 Sensor Slow Response – Rich to Lean (Bank 1 Sensor 2)
November 10, 2020
P013A Code: O2 Sensor Slow Response – Rich to Lean (Bank 1 Sensor 2)Oxygen sensors use electric signals to communicate with the PCM. These electrical signals should vary according to the oxygen concentration in the exhaust. The PCM relies on this data to determine if the engine is running lean (lacking fuel) or rich (too much fuel).
