  • The symptoms of the automobile fault code p1119 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p1119 can be caused by a faulty engine coolant temperature sensor, an open or shorted sensor harness, or a poor electrical connection in the sensor circuit.

  • The fault code P1119 can be caused by the following: a faulty Engine Coolant Temperature Sensor, an open or shorted harness for the Engine Coolant Temperature Sensor, and a poor electrical connection in the Engine Coolant Temperature Sensor circuit.

To fix fault code p1119, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p1119, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • The estimated repair time for this fix is 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p1119 are the estimated repair time of 1.0 hour and the typical hourly rate charged by auto repair shops, which ranges between $75 and $150.

The P1119 fault code refers to the Engine Coolant Temperature (ECT) sensor. This sensor is located in the left bank cylinder head near the front of the engine. It contains a semiconductor device called a thermistor, which changes resistance based on temperature.

The ECT sensor has a signal circuit and a ground circuit. The Powertrain Control Module (PCM) applies a voltage of about 5.0 volts on the signal circuit to the sensor. The PCM monitors changes in this voltage caused by changes in the resistance of the sensor to determine the engine coolant temperature.

When the engine coolant is cold, the sensor resistance is high, and the PCM senses a high signal voltage, indicating a low temperature. As the engine coolant warms up, the sensor resistance decreases, causing the signal voltage to be pulled down a greater amount.

The P1119 fault code indicates that the engine coolant temperature signal is out of range. This could be due to a faulty ECT sensor or a problem with the signal circuit or ground circuit.

It is important to diagnose and fix this issue to ensure proper engine performance and prevent potential damage.

What are the possible causes for the automobile fault code P1119?

If you see the engine light on or the service engine soon warning light, the fault code P1119 might be the culprit. This code is often caused by a faulty engine coolant temperature sensor, an open or shorted sensor harness, or a poor electrical connection in the sensor circuit. To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, look out for broken, bent, pushed out, or corroded pins in the connectors. Don’t forget to check the possible causes mentioned above for a comprehensive solution.

How can I visually inspect the wiring harness and connectors to fix the P1119 fault code?

If you’re dealing with the P1119 fault code and your engine light is on, it’s time to take action. The culprit could be a faulty engine coolant temperature sensor or issues with the sensor’s wiring harness and connectors. To fix this, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken or bent pins, corrosion, or components that are out of place. This simple step could be the key to resolving the issue and getting your engine running smoothly again.

What should I look for when checking for damaged components or corroded connector pins to resolve the P1119 fault code?

When resolving the P1119 fault code, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. These issues can cause a poor electrical connection or an open/short circuit in the Engine Coolant Temperature Sensor. By thoroughly checking for these problems, you can effectively address the cause of the fault code and resolve the issue.
