Why is Bank 1 sensor 2 low voltage?
The O2 sensor circuit for bank 1 sensor 2 is used to give a voltage feedback to the ECM showing how much oxygen is in the exhaust stream to help the engine control the fuel-to-air ratio better. The low voltage condition is excessive oxygen in the exhaust or problems causing the issue. Need help with a P0137 code?
How to set the camshaft position sensor circuit low?
Connect a third jumper to the signal circuit of the camshaft position sensor side of the harness. Idle the engine. Connect the DMM J 39200to the signal circuit (CMP side) and ground. Set the DMM to DC voltage and to the duty cycle position.
Where is the bank 2 O2 sensor located?
Error Code P0157: O2 Sensor Circuit Low Voltage (Bank 2 Sensor 2) Error Code P0157 is defined as O2 Sensor Low Voltage Bank 2 Sensor 2. This refers to a trouble in the Bank 2 Sensor 2 of the O2 (oxygen) sensor, which is located near the backside of the exhaust, behind the catalytic converter.
What is the diagnostic code for O2 sensor circuit low voltage?
Cost of diagnosing the P0137 code. P0137 is a diagnostic trouble code (DTC) for “O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What causes the camshaft position sensor to be incorrect?
These are both a result of an improper amount of fuel being injected into the cylinders since the PCM is getting incorrect information from the camshaft position sensor.
How much does a bad camshaft sensor cost?
In this case, because of an inaccurate reading from a bad camshaft position sensor, more fuel than necessary is injected into the engine which causes your fuel economy to drop. To replace a camshaft position sensor, you can expect to pay anywhere from $120 to $300. Parts alone will run about $50 to $200.
What does low voltage signal on PCM mean?
To achieve this, the PCM checks the oxygen content in the exhaust gases heading towards the catalytic converter. A low voltage signal from the oxygen sensor indicates low oxygen content in the exhaust—a sign that the engine runs rich. The PCM responds by reducing the fuel going to the engine.
What happens if a PCM sensor malfunctions?
The PCM relies on data from the oxygen sensor or air-fuel ratio sensor to regulate the engine’s fuel intake. If a sensor malfunctions, it will disrupt the proper operation of the engine. Occasionally, the vehicle may display no symptoms.
How does the ECM detect low voltage problems?
The ECM detects the low voltage problem and turns on the Check Engine Light. The ECM uses other O2 sensors to try and control the fuel injection with their values. What are the symptoms of the P0137 code? The engine will run rich during the testing of the sensor for problems. The Check Engine Light will be illuminated.
What is the O2 sensor code for bank 1?
All our repairs are backed by our 12-month / 12,000-mile warranty. P0137 is the OBD-II generic code indicating the O2 sensor for bank 1 sensor 2 is failing to increase the voltage output above .21 volts indicating excessive oxygen in the exhaust.
