The automobile fault code P1117 indicates a problem with the engine coolant system. Symptoms include the engine light being on and engine overheating.

The cause could be a low engine coolant level, a faulty engine coolant temperature sensor, an open or shorted sensor harness, poor electrical circuit connection, a faulty engine coolant thermostat, or a damaged powertrain control module. To fix the issue, visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.

The repair time is estimated to be 1.0.

It is important to address this issue promptly to prevent further damage to the engine.

If you’re experiencing an illuminated engine light and engine overheating, you may be dealing with the p1117 fault code.

  • The fault code p1117 is associated with the following symptoms: Engine Light ON (or Service Engine Soon Warning Light) and Engine Overheating.

The automobile fault code p1117 can be caused by a variety of factors, including low engine coolant level, a faulty engine coolant temperature sensor, and a damaged powertrain control module (PCM).

  • The fault code P1117 can be caused by: low engine coolant level, faulty engine coolant temperature (ECT) sensor, open or shorted ECT sensor harness, poor connection in the ECT sensor electrical circuit, faulty engine coolant thermostat, and a damaged powertrain control module (PCM).

To fix the p1117 fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p1117, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors for any damage.
  • Look for broken, bent, pushed out, or corroded pins in the connectors.
  • This fix should take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p1117 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 P1117 fault code refers to an intermittent issue with the Engine Coolant Temperature (ECT) Sensor.

This sensor is a thermistor device that measures the temperature of the engine coolant.

It works by changing its electrical resistance based on the temperature. The ECT sensor is a passive sensor, meaning it is connected to a voltage divider network.

As the resistance of the sensor changes, it causes a variation in the total current flow. The voltage drop across a fixed resistor determines the voltage signal sent to the Powertrain Control Module (PCM). The PCM uses the ECT input for fuel control and cooling fan control.

When the P1117 code is triggered, it means there is an intermittent issue with the ECT sensor.

This can lead to inaccurate temperature readings and affect the engine’s performance. It is important to address this issue promptly to ensure proper fuel control and cooling fan operation.

What are the possible causes of fault code P1117 in an automobile?

If you’re experiencing the engine light or service engine soon warning light coming on, along with engine overheating, it could be due to fault code P1117. This fault code can be caused by a few different factors, including low engine coolant level, a faulty engine coolant temperature (ECT) sensor, an open or shorted ECT sensor harness, poor electrical circuit connection of the ECT sensor, a faulty engine coolant thermostat, or a damaged powertrain control module (PCM). To fix this issue, it’s recommended to check the possible causes mentioned above, visually inspect the wiring harness and connectors, and look for any damaged components or corroded connector pins.

How can I identify and fix the low engine coolant level issue related to fault code P1117?

If you’re experiencing an engine light on or a service engine soon warning light, along with engine overheating, it could be due to a low engine coolant level. This issue is related to fault code P1117. To fix it, start by checking the possible causes mentioned above. Take a close look at the wiring harness and connectors, ensuring there are no visible damages. Also, check for any broken, bent, pushed out, or corroded pins in the connectors.

What steps should I take to inspect and repair the wiring harness and connectors associated with fault code P1117?

To inspect and repair the wiring harness and connectors associated with fault code P1117, start by visually inspecting the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Additionally, check the engine coolant level and the engine coolant temperature (ECT) sensor for any faults. If necessary, replace the faulty ECT sensor or engine coolant thermostat. Finally, ensure there are no poor connections in the ECT sensor electrical circuit and check for any damage to the powertrain control module (PCM).
