What is the correct reading with an ohm meter on an ECT sensor for 1991 Dodge 5.9L I have code 22 and replaced the sensor and still have code 22?

For a 1991 Dodge 5.9L, an ECT (Engine Coolant Temperature) sensor should typically read between 5,000 to 10,000 ohms at room temperature (around 77°F or 25°C). If you're still getting a code 22 after replacing the sensor, check the wiring and connectors for any damage or corrosion. Additionally, verify that the sensor is properly grounded and that the ECM (Engine Control Module) is functioning correctly. If everything checks out, the issue might lie with the ECM itself.
