The P040B would be set by the engine control module when the EGR temperature sensor would be not as per the factory specifications. The fault code P040B can be described as Exhaust Gas Recirculation Temperature Sensor ‘A’ Circuit Range/Performance.
What does the EGR temperature sensor do?
The EGR temperature sensor is an engine management sensor that is part of the EGR system. It works together with the EGR solenoid to control the flow of the EGR system. The sensor is installed in between the exhaust and intake manifold, and monitors the temperature of the exhaust gases.
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.
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 P042E mean?
What does OBD-II fault code P042E mean? OBD-II Code Decreased engine performance is defined as a Exhaust Gas Recirculation “A” Control Stuck Open. EGR (Exhaust Gas Recirculation) systems are used to reduce the combustion temperature, thus reducing emissions.
Where is the EGR temperature sensor located?
exhaust manifold
The EGR temperature sensor is usually mounted in the exhaust manifold or mounted near the EGR valve.
How much does it cost to replace the EGR sensor?
The average cost of replacing the EGR valve in your vehicle is anywhere from $250 to $350 on average, depending on your vehicle’s year, make, and model as well as the type of system it has. The cost of parts will be somewhere around $190 to $270, while the cost of labor will be anywhere from $60 to $80.
