How do you remove the exhaust temperature sensor?
How do you remove the exhaust temperature sensor?
How do I replace an exhaust gas temperature sensor?
- Locate the faulty sensor.
- Next disconnect the electrical connector and unscrew the sensor using a socket wrench, taking care not to damage nearby components.
- Prepare the new sensor, applying anti-seize compound to the thread where necessary.
Where is the exhaust gas temperature sensor located?
The exhaust gas temperature (EGT) sensors are variable resistors that measure the temperature of the exhaust at the inlet and outlet of the diesel particulate filter (DPF). The engine control module (ECM) supplies a bias 5-volt signal to the EGT signal circuit, and supplies a ground to the low reference circuit.
What should the EGT sensor 2 be on a Duramax?
This DTC runs continuously when the above condition is met. The ECM detects that the EGT sensor 2 is less than 0.32 volt for greater than 1 second. The ECM detects that the EGT sensor 2 is greater than 3.37 volts for greater than 1 second.
What kind of exhaust system does a Silverado have?
The diesel exhaust system on 2017-2018 Silverado and Sierra models and 2019-2020 Silverado 2500/3500 and Sierra 2500/3500 models equipped with the 6.6L Duramax diesel engine (RPO L5P) (Fig. 1) requires an occasional Diesel Particulate Filter (DPF) cleaning. Under normal driving conditions, the DPF cleaning occurs without any driving involvement.
What happens if the EGT sensor does not work?
On these vehicles, the circuit board welds on the EGT sensors in the exhaust system may not be to GM specification. If a weld fails, the Service Engine Soon light will illuminate in the instrument panel, the exhaust gas may not be filtered properly, and the engine power may be reduced.
Where are the O2 sensors located on a Chevy Silverado?
The upstream sensors are located between the exhaust manifold and the exhaust, while the downstream sensors are located after the catalytic converter. Upstream driver’s side O2 sensor: Bank 1, Sensor 1 (B1/S1) Upstream passenger’s side O2 sensor: Bank 2, Sensor 1 (B2/S1) Downstream driver’s side O2 sensor: Bank 1, Sensor 2 (B1/S2)
The exhaust gas temperature (EGT) sensors are variable resistors that measure the temperature of the exhaust at the inlet and outlet of the diesel particulate filter (DPF). The engine control module (ECM) supplies a bias 5-volt signal to the EGT signal circuit, and supplies a ground to the low reference circuit.
What kind of O2 sensor does a Duramax use?
Duramax does not use oxygen (O2) sensors. Perhaps you’re thinking of a nitrogen oxide (NOx) sensor? In which case, the location of NOx sensor 1 (there’s only one exhaust bank) is indicated by 1 on this diagram (diagram goes from engine on the left to tail pipe on the right).
Where is the NoX sensor in the exhaust?
In which case, the location of NOx sensor 1 (there’s only one exhaust bank) is indicated by 1 on this diagram (diagram goes from engine on the left to tail pipe on the right). The location of NOx sensor 2 is indicated by 7. NOx sensor 1 is located on the exhaust but should be in the engine department still.
