P0062 Code – What Does It Mean & How To Fix It

This is one of the most frequent OBD2 trouble codes. Read the full article below to know what it means, how to fix it, and what other codes may show related to it.

Definition

The P0062 DTC code is associated with a malfunction in the intake manifold air control solenoid circuit (Low Voltage). This code is typically encountered in vehicles equipped with an OBD-II system, which monitors the performance of various components, including the intake manifold air control solenoid.

Meaning

The intake manifold air control solenoid circuit has experienced low voltage, as indicated by the P0062 code, which has been identified by the electronic control module (ECM). In order to optimize the air-fuel combination for effective combustion, this circuit controls the airflow into the intake manifold.


Causes

The P0062 DTC code may be caused by a number of factors, including:

  • A faulty solenoid in the intake manifold air control system might result in a low voltage situation in the circuit.
  • Wire problems: Corroded, damaged, or loose wire and connections may cause the circuit to be broken, resulting in low voltage.
  • Short or open circuit: A low voltage condition might result from a short or open circuit in the intake manifold air control solenoid circuit.
  • ECM malfunction: On occasion, a malfunctioning ECM may falsely identify a low voltage condition and set off the code.

Symptoms

Common symptoms associated with the P0062 DTC code may include:

  • Illuminated check engine light (MIL)
  • Reduced engine performance or power
  • Rough idling or stalling
  • Engine hesitation or surging
  • Decreased fuel efficiency

Diagnosis

The following actions will normally be taken by a skilled technician in order to effectively diagnose the P0062 code:

  • Using a diagnostic scanner, find the precise issue code(s).
  • Inspect the intake manifold air control solenoid's wiring and contacts.
  • Use a multimeter to check the solenoid's resistance and operation.
  • Examine the ECM's operation and any possible communication problems.

Common mistakes

Common errors that need to be avoided when dealing with the P0062 DTC code are:

  • Neglect to address additional relevant codes or issues that can arise at the same time. 
  • In order to confirm the failure of the solenoid, the intake manifold air control solenoid must be replaced without proper testing. - 
  • Overlooking wiring and connector problems, which may be the root cause of the low voltage condition.

How serious is this?

The P0062 code may not be immediately detrimental, yet it is important to take this into account. Failure to address this issue may lead to a reduction in engine performance, reduced fuel efficiency, and possible adverse effects on the rest of the components over time. In order to avoid further complications, it is recommended that the code be addressed as soon as possible.

What repairs can fix the code?

repair manuals

Possible repairs are as follows to solve the P0062 DTC code: 

If it fails to test, replace the faulty solenoid on the intake manifold's air control unit. 

To repair or replace broken wires and couplings associated with the solenoid circuit. 

With a view to tackling any short and open circuits in the circuit. In rare cases, if diagnosed as a cause, replacement of the defective ECM.

Related codes

Other related codes that may be encountered alongside or instead of P0062 include:

  • P0060: Intake Manifold Air Control Solenoid Circuit Malfunction
  • P0061: Intake Manifold Air Control Solenoid Circuit Performance
  • P0063: Intake Manifold Air Control Solenoid Circuit High Voltage

Conclusion

The P0062 DTC code indicates a low voltage condition in the intake manifold air control solenoid circuit. You will be able to efficiently deal with this problem by taking into account its meaning, causes, symptoms, diagnosis procedures, common errors, seriousness, potential remedial measures, and associated codes. If you are not sure or in need of help to diagnose and resolve the P0062 DTC code, it is recommended that you contact a professional mechanic.
