Fix P213C: STEP-BY-STEP diagnostic GUIDE!

The P213C: Exhaust Gas Recirculation (EGR) Throttle Control Circuit ‘B’ Low indicates that the voltage in the EGR throttle control circuit ‘B’ is lower than expected. This could be caused by a faulty EGR throttle control, wiring issues, or an electrical fault affecting the performance of the system.

P213C – Quick Overview

CodeInformation
MeaningP213C: Exhaust Gas Recirculation Throttle Control Circuit ‘B’ Low
Is it serious?Yes, it can cause improper EGR function, leading to performance issues and increased emissions.
Possible causes– Low voltage in the EGR throttle control circuit ‘B’
– Faulty EGR throttle control
– Wiring issues
How to diagnose?– Measure voltage in the EGR throttle control circuit ‘B’
– Test the EGR throttle control
– Inspect wiring and connections

P213C Meaning

The P213C code indicates that the EGR throttle control circuit ‘B’ is experiencing low voltage, which can prevent the proper operation of the exhaust gas recirculation system. This could lead to increased emissions, poor engine performance, and drivability issues. The cause is often linked to faulty wiring or a malfunctioning EGR throttle control.

Step-by-step diagnostic guide

ActionDescriptionTools Needed
Check for Other CodesUse an OBD-II scanner to check for other related codes that may provide further information about the EGR system’s overall condition.OBD-II Scanner
Measure Voltage in the CircuitUse a multimeter to measure the voltage in the EGR throttle control circuit ‘B’. Compare the readings with manufacturer specifications to determine if the voltage is too low.Multimeter
Test the EGR Throttle ControlUse a diagnostic tool to test the operation of the EGR throttle control and ensure it is functioning within the expected parameters. Replace if necessary.Diagnostic Tool
Inspect Wiring and ConnectionsVisually inspect the wiring and connectors leading to the EGR throttle control ‘B’ for signs of damage, loose connections, or corrosion. Repair or replace as necessary.Flashlight, Multimeter
Check for Shorts or Open CircuitsPerform continuity tests on the wiring leading to the EGR throttle control ‘B’ to detect any shorts or open circuits that could cause low voltage. Repair as needed.Multimeter, Wiring Diagram
Clear the Code and Test DriveAfter repairs or adjustments, clear the code using an OBD-II scanner and take the vehicle for a test drive to confirm the issue is resolved.OBD-II Scanner
Recheck for CodesAfter the test drive, re-scan the vehicle to ensure the P213C code has not returned.OBD-II Scanner
