P1914 Trans Temp Sensor Circuit Open or Shorted to Pwr or Gnd

How to Diagnose and Solve P1914 Trans Temp Sensor Circuit Open or Shorted to Pwr or Gnd Issues


As a seasoned car expert, I understand the frustration that comes with encountering a **P1914 Trans Temp Sensor Circuit Open or Shorted to Pwr or Gnd** issue. This problem can be a real headache, but don’t worry, I’m here to help you diagnose and solve it.

Understanding the P1914 Code

Before we dive into the solution, let’s first understand what the **P1914 code** means. This code is a generic powertrain diagnostic trouble code (DTC) that indicates a problem with the transmission temperature sensor circuit.

What Causes the P1914 Code?

The P1914 code is usually triggered by a few common issues. These include a faulty transmission temperature sensor, damaged wiring or connectors, or a malfunctioning powertrain control module (PCM).

Diagnosing the P1914 Code

Now that we understand the potential causes, let’s move on to diagnosing the problem.

Step 1: Visual Inspection

Start by visually inspecting the wiring and connectors around the transmission temperature sensor. Look for any signs of damage, corrosion, or loose connections.

Step 2: Use a Diagnostic Scanner

Next, use a diagnostic scanner to read the fault codes from the PCM. This will help you identify if there are any other related issues that might be causing the P1914 code.

Step 3: Test the Transmission Temperature Sensor

You can test the transmission temperature sensor using a digital multimeter. If the sensor is faulty, it will need to be replaced.

Solving the P1914 Code

After diagnosing the problem, it’s time to solve it.

Step 1: Replace Damaged Wiring or Connectors

If you found any damaged wiring or connectors during your visual inspection, these will need to be replaced.

Step 2: Replace the Transmission Temperature Sensor

If the transmission temperature sensor is faulty, replace it with a new one.

Step 3: Reset the PCM

After making the necessary repairs, reset the PCM to clear the P1914 code. This can be done using a diagnostic scanner.


Dealing with a **P1914 Trans Temp Sensor Circuit Open or Shorted to Pwr or Gnd** issue can be daunting, but with the right knowledge and tools, you can diagnose and solve this problem yourself. Remember, if you’re ever in doubt, it’s always best to consult with a professional mechanic.
