What is code P242A?

What is code P242A?

OBD Code P242A – Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 3. <<See All OBD Codes. The trouble code P242A can be explained as Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 3. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles.

Where is the exhaust gas temperature sensor located?

The exhaust gas temperature sensor (EGTS), which is located in front of Diesel Oxidation Catalyst (DOC) and/or in front of Diesel Particulate Filter (DPF), detects exhaust gas temperature and converts it into a voltage and feedback engine ECU with the voltage signal in order to control engine condition to effectively …

How does an exhaust gas temperature sensor work?

How do exhaust gas temperature sensors work? The NTC element has a high resistance at low temperatures and a low resistance at high temperatures. In other words, its resistance decreases as the temperature increases. Whereas in a PTC element, the most common type, resistance increases in line with temperature.

What does P0544 code mean?

The P0544 code means that the powertrain control module (PCM) has detected a problem with the exhaust gas temperature sensor circuit.

Can you clean an exhaust gas temperature sensor?

Handle the exhaust gas temperature sensor carefully, dropping the component may cause unseen damage to the cement that secures the thermistor. 3. If the sensor is threaded, clean the thread in the exhaust pipe with a cleaning tap.

What causes high exhaust gas temperature?

High exhaust gas temperatures are caused by too much fuel and too little air within the diesel motor’s cylinders. Facilitate the efficient consumption of fuel, and lowered exhaust temperatures, by allowing more clean air to flow into the motor and reset the appropriate air to fuel ratios.

What is a high exhaust temp?

At rich air-fuel ratio, the exhaust gas temperature either increases or decreases depending on the fuel. High temperatures (typically above 1,600 °F or 900 °C) can be an indicator of dangerous conditions that can lead to catastrophic engine failure.

What causes high exhaust temp?

Fouling of the turbine side of the turbocharger is a common cause for high exhaust gas temperatures. The sequence of events is often as follows: → Fouling of turbine (coke deposit) → Bad turbocharger performance → Lower airflow and charge air pressure → Higher exhaust gas temperatures.
