This error code refers to a malfunction in the exhaust gas temperature circuit.
What is code P242D?
The Exhaust Gas Temperature (EGT) Sensor tells the engine control module (PCM) the temperature of the exhaust gas going into and out of the Selective Catalytic Reduction (SCR). If the PCM detects an implausible signal from the EGT sensor, it will store code P242D.
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 P0405 code mean?
Exhaust Gas Recirculation Sensor A
What does OBD-II fault code P0405 mean? OBD-II Code P0405 is defined as a Exhaust Gas Recirculation Sensor A Circuit Low. NOx gases, which are a leading cause of acid rain and in some people, respiratory problems, are formed when the engine combustion temperatures become too high (2500° F).
