P213C Fault Code

Exhaust Gas Recirculation Throttle Control Circuit B Low

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

The P213C fault code indicates an issue with the Exhaust Gas Recirculation (EGR) throttle control circuit, specifically Circuit B being low. This can lead to improper EGR operation, which affects engine efficiency and emissions. Understanding this code is crucial for diagnosing and rectifying issues in the EGR system.

What are the symptoms of the P213C code?

Common symptoms associated with a P213C fault may include:

• Check Engine Light (CEL) illuminated on the dashboard
• Rough idle or engine stalling
• Decrease in fuel efficiency
• Increased emissions during smog tests
• Unusual engine noises related to EGR operation

What causes the P213C code?

The primary causes of a P213C code include:

• Faulty EGR throttle position sensor
• Damaged wiring or poor connections within Circuit B
• Faults in the Engine Control Module (ECM)
• Blockages or leaks in the EGR system
• Malfunctioning throttle body

How to fix P213C?

To resolve a P213C code, follow these steps:

• Inspect and repair any damaged wiring or connections in the EGR throttle control circuit.
• Test the EGR throttle position sensor for proper functionality and replace it if necessary.
• Clean or replace any blocked components in the EGR system, ensuring it is free of carbon buildup.
• If applicable, reprogram or replace the ECM to rectify any internal faults.
