2. **Poor Performance**: Your car may struggle to accelerate, or it may stall or misfire.
3. **Difficulty Starting**: If your car is having trouble starting, it could be due to this fault.

Diagnosing a P1782 Ignition Retard Request Circuit Fault

Now that we know what to look for, let’s get into how to diagnose this issue.

Step 1: Use an OBD-II Scanner

The first step is to use an **OBD-II scanner**. This device can read the fault codes from your car’s computer and help you identify the problem.

Step 2: Check the Wiring and Connectors

Next, check the wiring and connectors related to the ignition retard request circuit. Look for any signs of damage or corrosion.

Step 3: Inspect the Sensors

Inspect the sensors related to the ignition retard request circuit. If they are faulty, they may need to be replaced.
