OBD error code P247A will be set by your vehicle’s PCM when it detects an incorrect signal. Your car’s pcm is responsible for monitoring the egt sensor and to make sure that the circuit and range values are within the specifications.
How does an exhaust gas temperature sensor work?
The exhaust gas temperature sensor detects the temperature, for example, in front of the catalytic converter or diesel particulate filter and sends this as a voltage signal to the engine control unit.
What does P0544 code mean?
exhaust gas temperature sensor circuit
P0544 code definition
The P0544 code means that the powertrain control module (PCM) has detected a problem with the exhaust gas temperature sensor circuit.
What does P2084 code mean?
The P2084 diagnostic trouble code is an indication that there is a range/performance issue of the exhaust gas temperature (EGT) sensor 2 circuit on Bank 1. The EGT sensor monitors the temperature of exhaust gas and sends this information to the powertrain control module (PCM) through a voltage signal.
What does code P040D mean?
Exhaust Gas Recirculation Temperature Sensor
OBD-II Code P040D is defined as a Exhaust Gas Recirculation Temperature Sensor “A” Circuit High. An Exhaust Gas Recirculation (EGR) Temperature Sensor is an electrical sensing probe that monitors EGR temperature going in and out of the EGR Cooler and transmits the signal to the engine control control module.
Where is the exhaust gas temperature sensor located?
Generally, one temperature sensor is located on the exhaust manifold, and one is located near the EGR valve. The typical symptoms of a failed EGR temperature sensor include pinging, increased emissions and an illuminated Check Engine Light.
Can a faulty exhaust temperature sensor symptoms?
A faulty exhaust gas temperature sensor can negatively affect a vehicle’s after-treatment system, resulting in the following symptoms: Check engine light: if the ECU detects a problem with the sensor or signal, it will trigger the check engine light to come on.
