Standard Ignition Exhaust Gas Temperature (EGT) Sensor P/N:ETS178
Keep tabs on exhaust temperature with the Standard Ignition Exhaust Gas Temperature (EGT) Sensor ETS122. This EGT sensor measures the temperature of the exhaust gas and reports it to the powertrain control module, which uses the reading to manage functions such as emissions control and diesel aftertreatment. It installs as a direct-fit replacement for the 2013-2018 RAM 2500, 2013-2018 RAM 3500, 2015-2018 RAM 4500, and 2015-2018 RAM 5500 — see the Buyer's Guide tab for the full engine-level fitment.
If a failed EGT sensor is the cause of a stored temperature-circuit code or reduced-power/limp condition, replacing it with the ETS122 restores the original sensing function. Diagnose the cause before replacing.
