How to Fix P1102 1-4 Upshift (Skip Shift) Solenoid Control Circuit Malfunction

Introduction

If you own a car, you know how frustrating it can be when something goes wrong. One of the most common issues that car owners face is a malfunctioning solenoid control circuit. In this article, we will discuss how to fix the P1102 1-4 Upshift (Skip Shift) Solenoid Control Circuit Malfunction.

What is a Solenoid Control Circuit?

A solenoid control circuit is an electrical circuit that controls the operation of a solenoid. A solenoid is an electromechanical device that converts electrical energy into mechanical energy. In a car, solenoids are used to control various functions, such as shifting gears, opening and closing valves, and engaging the starter motor.

What is the P1102 1-4 Upshift (Skip Shift) Solenoid Control Circuit Malfunction?

The P1102 1-4 Upshift (Skip Shift) Solenoid Control Circuit Malfunction is a diagnostic trouble code (DTC) that indicates a problem with the solenoid control circuit. This code is specific to vehicles with automatic transmissions and is usually caused by a faulty solenoid or a wiring issue.

How to Fix the P1102 1-4 Upshift (Skip Shift) Solenoid Control Circuit Malfunction

To fix the P1102 1-4 Upshift (Skip Shift) Solenoid Control Circuit Malfunction, follow these steps:

Step 1: Check the Wiring

The first step is to check the wiring for any damage or corrosion. Start by inspecting the wiring harness for any visible damage or wear. If you find any damage, replace the affected wiring.

Step 2: Check the Solenoid

The next step is to check the solenoid for any damage or wear. Start by disconnecting the solenoid from the wiring harness. Then, use a multimeter to test the resistance of the solenoid. If the resistance is outside of the manufacturer’s specifications, replace the solenoid.

Step 3: Replace the PCM

If the wiring and solenoid are both in good condition, the problem may be with the powertrain control module (PCM). The PCM is the computer that controls the operation of the engine and transmission. If the PCM is faulty, it may be causing the P1102 1-4 Upshift (Skip Shift) Solenoid Control Circuit Malfunction. In this case, the PCM will need to be replaced.

Conclusion

Fixing the P1102 1-4 Upshift (Skip Shift) Solenoid Control Circuit Malfunction may seem daunting, but with the right tools and knowledge, it can be done. By following the steps outlined in this article, you can diagnose and fix the problem, ensuring that your car runs smoothly and safely.
