P2034 is a diagnostic trouble code (DTC) for "Exhaust Gas Temperature Sensor Circuit Bank 2 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. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
P2204 is a generic OBD-II diagnostic trouble code (DTC) referencing a malfunction with the exhaust gas temperature (EGT) circuit. This code may be seen with other EGR codes.
The P2024 means that the circuit for the exhaust gas temperature sensor bank 2 sensor 2 has experienced a malfunction. The engine control module (ECM) is constantly looking for faults and when the exhaust gas temperature fault for bank 2 sensor 2 is found, then the P2024 code is set. The Check Engine Light will be shown on the dashboard. With the Check Engine Light, the ECM will set a failsafe mode, which is used to prevent the vehicle from further damage. This will remain until the code is resolved or normal sensor data is found.
The P2024 code has a few typical causes:
Generally, the symptoms are minor for the P2024 code. In all cases, the Check Engine Light will be seen on the dashboard, but other than that, no other symptoms are normally noticed.
We will begin by using a scan tool to check for any codes in the vehicle's ECM. There may be current, pending, or history codes so note all of them. Look at the freeze frame data for each code, then clear all the codes.
Once all codes are cleared, take a vehicle on a test drive to confirm the Check Engine Light comes back on. Once the code reappears, check what codes are stored this time around.
Next, perform a visual inspection looking for visually damaged or broken components. Then the scan tool will be used to check the bank 2 sensor 2 exhaust gas temperature readings and compare them to bank 1.
Then, a multimeter is used to check the EGT bank 2 sensor 2 resistance. If nothing else is seen, then a temperature gauge is used to assess the accuracy of the EGT sensor readings.
The most common mistake seen is replacing components before actually diagnosing the fault to find the cause. This often leads to wasted time and effort replacing components that may not actually fix the vehicle.
The P2024 code is not very serious in terms of driveability problems and should not prevent the operation of the vehicle. Though the code it is not serious by itself, it should still be repaired as soon as possible.
Common repairs are:
An advanced level scan tool is a needed tool for this code. This allows much more info than a general scan tool and access to the live datastream.
Along with the scan tool, an infrared thermometer is used to check the exhaust gas temperature and then compare it to the readings the ECM tells you. They should be very close.
