2000 Volkswagen Jetta Engine Codes P0117 [Answered]

P0117 is a common Volkswagen Jetta engine code that indicates a problem with the coolant temperature sensor. This sensor is responsible for sending information to the engine control unit (ECU) about the temperature of the coolant in the engine. If the sensor is faulty, the ECU may not be able to properly regulate the engine temperature, which can lead to a number of problems.

In this article, we’ll take a closer look at P0117, what it means, and how to fix it. We’ll also provide some tips on how to prevent this code from occurring in the future.

So 2000 Volkswagen Jetta Engine Codes P0117

P0117 Volkswagen Jetta

P0117 is a Volkswagen OBD-II code that indicates the coolant temperature sensor circuit has a high input. This can be caused by a faulty coolant temperature sensor, a wiring issue, or a problem with the engine control module.

Symptoms of P0117 include:

Engine temperature gauge reading higher than normal
Engine running hot
Check engine light illuminated

To diagnose P0117, a technician will use a scan tool to read the diagnostic trouble codes DTCs and perform a visual inspection of the wiring and connectors for the coolant temperature sensor. The technician may also need to test the sensor itself to verify that it is functioning properly.

The fix for P0117 typically involves replacing the coolant temperature sensor or repairing any wiring issues. In some cases, the engine control module may need to be reprogrammed.

What is the P0117 code?

The P0117 code is a generic OBD-II code that indicates that the coolant temperature sensor (CTS) has gone bad. This code can be set on any vehicle that has a CTS, which is most vehicles made after 1996. The CTS is a sensor that measures the temperature of the coolant in the engine. This information is used by the engine control module (ECM) to calculate the air-fuel ratio and to adjust the ignition timing.

What are the symptoms of the P0117 code?

The symptoms of the P0117 code can vary depending on the vehicle. Some of the common symptoms include:

Engine misfires
Poor fuel economy
Engine overheating
Check engine light illuminated

How is the P0117 code diagnosed?

The P0117 code can be diagnosed using a scan tool. The scan tool will be able to read the code and provide information about the freeze frame data. The freeze frame data will show the engine coolant temperature at the time the code was set.

The technician will also need to visually inspect the CTS. The CTS is located in the engine coolant passage. The technician will need to check the CTS for damage or corrosion. The technician will also need to check the wiring harness for damage or corrosion.

How is the P0117 code repaired?

The P0117 code can be repaired by replacing the CTS. The CTS is a relatively inexpensive part and it is usually easy to replace. The technician will need to disconnect the battery before replacing the CTS. The technician will then remove the old CTS and install the new CTS. The technician will then reconnect the battery and clear the code from the ECM.

What are the potential consequences of ignoring the P0117 code?

If the P0117 code is ignored, the engine may continue to run poorly. This can lead to decreased fuel economy, engine overheating, and engine damage. The check engine light will also remain illuminated, which can be annoying.

How can I prevent the P0117 code from happening again?

There are a few things you can do to prevent the P0117 code from happening again:

Keep the coolant level in the engine topped off.
Inspect the CTS for damage or corrosion regularly.
Replace the CTS if it is damaged or corroded.
Avoid driving the vehicle in extreme temperatures.
