In most cases, it's the sign of a bad downstream oxygen sensor. A p2a01dodge ram 6.7l cummins o2 sensor and heat shield servicethis code indicates performance issues with the downstream o2 sensor, which is part of the inspection and. P0138 indicates your downstream oxygen sensor's voltage is too high
How to Change an Oxygen Sensor: A Comprehensive Step-by-Step Guide
Click here to know possible causes and how to repair them.
Code p0138 is set when the downstream sensor sends too high of a voltage signal for an extended period of time
Too high typically means higher than 1.1 volts, which is very high for a. Comprehensive guide to fixing dtc p0138 Identify causes, test the o2 sensor circuit with a multimeter, and execute the final repair. The p0138 code indicates high voltage in the o2 sensor circuit
Learn its causes, symptoms, and fixes to keep your vehicle running smoothly. Understand the p0138 code meaning and follow expert steps to test the o2 sensor circuit and resolve high voltage readings. What does the p0138 oxygen sensor circuit high voltage (bank 1, sensor 2) mean P0138 code gets triggered when the engine control module detects that the voltage from the oxygen.
When your vehicle stores a p0138 code, it means that the downstream oxygen sensor experienced a high voltage reading
When the voltage is high at this sensor, it means that the balance.
