What causes P0138 code?
Diagnostic trouble code (DTC) P0138 stands for O2 Sensor Circuit High Voltage (Bank 1, Sensor 2). The code will set when your car’s primary computer—also called the powertrain control module (PCM)—detects that, for a given period of time, the voltage signal from the rear O2 sensor is too high.
Should you replace O2 sensors when you replace catalytic converter?
O2 sensor is an emission system part. If their contention is that the sensor is good but can’t be safely removed and replaced without damage when replacing the cat, that’s their problem not yours. It should be done on their time and shouldn’t cost you.
What side is bank 2 on 5.7 Hemi?
Hello. The Bank 2 Sensor 2 oxygen sensor should be the lower sensor on the passenger side. Lower meaning after the catalytic converter.
How do I know if my catalytic converter needs to be replaced?
Among the symptoms of a bad catalytic converter are:
- Sluggish engine performance.
- Reduced acceleration.
- Dark exhaust smoke.
- The smell of sulfur or rotten eggs from the exhaust.
- Excessive heat under the vehicle.
What does system Too Lean bank 1 and 2 mean?
If you have codes stored in the engine computer for lean bank 1 and 2 is caused by the entire engine is running lean. This is caused by not enough fuel getting into the engine or too much unmetered air getting into the engine and the computer cannot compensate anymore to run it normal.
What causes the p0138 O2 sensor code on a Dodge Ram?
P0138 is a common OBDII code that occurs in many vehicles, including theDodge Ram. The code is triggered when: The voltage at the sensor remains above threshold for 20 seconds or more; Voltage to the sensor is to high (wiring problem, think short) Bad O2 sensor itself; There are also some less likely problems that can cause P0138.
What does the DTC code p0138 mean on a car?
Diagnostic trouble code (DTC) P0138 stands for O2 Sensor Circuit High Voltage (Bank 1, Sensor 2). The code will set when your car’s primary computer—also called the powertrain control module (PCM)—detects that, for a given period of time, the voltage signal from the rear O2 sensor is too high.
How much does it cost to fix a p0138 code?
Most auto repair shops charge between $75 and $150 per hour. | When is the P0138 DODGE code detected? The P0138 code is set when the Engine Control Module (ECM) detects that the rear O2 sensor signal voltage remains excessively high for an extended period of time.
What is the OBDII code on a Dodge Ram?
P0138 is a common OBDII code that occurs in many vehicles, including the Dodge Ram. The code is triggered when: The voltage at the sensor remains above threshold for 20 seconds or more
