What does the OBD code p0136 stand for?
The onboard diagnostic (OBD) code P0136 is defined as an Oxygen Sensor Circuit Low Voltage in Bank 1, Sensor 2. It refers to the second oxygen sensor in Bank 1 of the engine, which is on the side of the engine with the #1 cylinder.
When is the p0140 code detected in the engine?
When is the P0140 code detected? The P0140 code is set when the voltage signal sent from the sensor to the Engine Control Module is constant. The heated oxygen sensor 2 (HO2S), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank.
When to set p0136 on HO2 sensor?
If the ECM detects low HO2Sensor voltage for an extended period, it will set P0136 Conditions required to set: HO2 sensor voltage is low for longer than 2 minutes (minutes depend on model of vehicle. Could be up to 4 minutes) There may be no visible symptoms to the driver.
What does the p0136 code on bank 1 mean?
Essentially the same as P0137, a P0136 code refers to the second oxygen sensor on Bank 1. The O2 oxygen sensor produces a voltage between 0.1 V and 0.9 V. The ECM monitors O2 sensor voltage and determines if exhaust is lean or rich. O2 sensor voltage is high when exhaust is rich and low when exhaust is lean.
When is the P0140 code detected? The P0140 code is set when the voltage signal sent from the sensor to the Engine Control Module is constant. The heated oxygen sensor 2 (HO2S), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank.
What causes the p0138 code on an engine?
What causes the P0138 code? 1 The engine control module (ECM) sees the voltage of the O2 sensor for bank 1 sensor 2 above 1.2 volts… 2 The ECM detects the voltage high problem and turns on the Check Engine Light. 3 The ECM uses other O2 sensors to try and control the fuel injection with their values.
What does p0141 mean in Powertrain Control Module?
Code P0141 occurs when the powertrain control module tests the downstream heated oxygen sensor’s heater circuit on Bank 1 and detects a short in the circuit or excessive resistance in the heater circuit. P0141 Symptoms Check Engine Light is on
