P2534 Fault Code

Ignition Switch Run/Start Position Circuit Low

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2534 fault code indicates an issue with the ignition switch's run/start position circuit, specifically that the circuit is interpreting a low voltage signal. This can disrupt the normal operation of the ignition system, affecting the vehicle's ability to start or run correctly.

What are the symptoms of the P2534 code?

Symptoms to look for when this code appears:

• The vehicle may not start at all.
• The engine could crank but not start, indicating a potential issue with the ignition system.
• Intermittent engine performance issues while driving.
• Warning lights on the dashboard may illuminate, particularly the check engine light.

What causes the P2534 code?

Common causes of the P2534 fault code include:

• A faulty ignition switch that is not properly sending signals to the vehicle's computer.
• Wiring issues, such as damaged or corroded wires in the ignition circuit.
• Poor connections at the ignition switch or related components.
• Issues within the powertrain control module (PCM) that may be misinterpreting signals.

How to fix P2534?

To resolve the P2534 fault code, follow these steps:

1. Inspect the ignition switch for signs of failure or damage and replace it if necessary.
2. Check all wiring and connections related to the ignition system for any signs of wear or corrosion.
3. Use a multimeter to test the voltage and continuity of the ignition switch circuit.
4. If problems persist, consider scanning for other error codes or testing the PCM to ensure it’s functioning correctly.
