Exhaust Gas Temp Sensor Circuit High (Bank 2 Sensor 2)
The P2026 trouble code indicates that the Engine Control Module (ECM) has detected a malfunction in the exhaust gas temperature (EGT) circuit coming from the second oxygen sensor in the second bank of exhaust.
Causes of the P2026 trouble code may include: * Damaged wiring or connectors that are associated with the oxygen sensor * A faulty oxygen sensor * An exhaust leak in just the right spot * An exhaust system that does not comply with the manufacturer’s original specifications * A faulty ECM
A mechanic would begin diagnosing the P2026 trouble code by locating the second (downstream) oxygen sensor on the second bank of exhaust (the side opposite of cylinder one).
Once this sensor is found, the mechanic would then visually inspect it and its circuitry. If any damages were found to the sensor or the sensor’s wiring, this would be replaced first before checking any other issues.
If no issues are found here, the mechanic would then check for exhaust leaks and to ensure that the vehicle is still equipped with the original exhaust system, or one that at least meets factory specifications. If any issues were found during this check, a portion of or the entire exhaust system may require replacement to correct this issue.
Finally, if no issues were found with the exhaust system itself, the last thing the mechanic would test is the Engine Control Module, which is the most unlikely cause of this issue.
The most common mistake that could be made would be to replace one or more oxygen sensors without properly testing them. Any time a code is stored related to an oxygen sensor, most people automatically assume that the sensor is bad. This can in fact indicate the exact opposite, and the sensor could be performing exactly as it should.
The P2026 trouble code is not very serious; the worst possible symptom that could occur would be a slight decrease in fuel mileage. It is still always best to get Check Engine Light codes diagnosed and repaired as soon as possible to prevent further damage later on.
Although this is not a serious issue, it is an issue that can be resolved very easily in most cases. An oxygen sensor is one of the most common causes of this trouble code. An oxygen sensor is fairly inexpensive in relation to other parts of a car. If the issue at hand is in fact related to the oxygen sensor or its wiring, and neither are very expensive compared to an engine, why not just fix the problem?
