Guide To P0082 OBD Error Code Solutions
OBD Code P0082 - Intake Valve Control Solenoid Circuit Low (Bank 2)
Are
you experiencing decreased engine performance and acceleration? Is there a
problem of reduced fuel economy? Is your car’s Check Engine Light On and the
vehicle is going into failsafe mode? Then, there can be a problem of OBD Code
P0082 being stored in the Powertrain Control Module (PCM) of the vehicle.
OBD
Code P0082 is defined as an Intake Valve Control Solenoid Circuit Low (Bank 2)
Learn More About OBD Error Code P0082
Whenever
there is an issue of Intake Valve Control Solenoid Circuit Low in the engine
Bank 2, the PCM stores the OBD code P0082 and flashes it.
Bank
2 refers to the side of the engine that does not contain cylinder 1 - be sure
to verify according to manufacturer’s specifications. The intake valve control
solenoid is usually located on the intake manifold side of the cylinder head.
This code is similar to codes P0081 and P0083. This code may also be
accompanied by P0028.
This
problem is specific to engine Bank 2 and occurs with the inconsistent
performance from the intake valve control solenoid. This can impact the
engine’s performance as the PCM is unable to control the opening and closing of
the exhaust valve properly and is unable to improve the engine’s fuel
consumption adequately.
This
sets a Check Engine Light on the dash and puts the vehicle into a failsafe
mode. In addition, the variable valve timing system is disabled until the
intake valve solenoid bank 2 proper range is detected.
What causes the problem of
Intake Valve Control Solenoid Circuit Low (Bank 2)?
- Problematic
intake valve control solenoid bank 2
- Open/Shortage
in Solenoid wiring/harness
- Faulty
ECM/PCM
- Damaged/faulty
electrical connection to the solenoid and circuit
Replace/Repair These Parts To Fix OBD Code P0082
- Engine Control
Module - Faulty ECM will affect the exhaust system and
this the engine performance and output. Replace faulty ECM components
immediately.
- Variable Valve
Timing - Faulty/damaged VVT will reduce the performance,
fuel economy or emissions of the vehicle. Thus, it is important to replace it
immediately.
- Intake Manifold
Solenoid - If the solenoid is faulty, it can affect the air
intake system and thus, it is important to replace it now!
- Diagnostic Tools - Factory grade diagnostic and scan tools are necessary to treat the OBD Code P0082 error correctly.
Symptoms Of OBD Error Code P0082
If
the Engine Control Module (ECM) detects the low voltage in the bank 2 control
solenoid and this causes a Check Engine Light to be illuminated on the
dashboard.
The
ECM also puts the vehicle into a failsafe mode to protect the car and prevent
damage. This failsafe mode disables the variable valve timing system.
Common Symptoms
- Lack
of acceleration
- Loss
of engine power
- Reduced
fuel economy
- Check
Engine Light Illumination
- Increased
emissions
How To Correct P0082 Intake Valve Control Solenoid Circuit Low (Bank 2)
Following are the major components that
when replaced or repaired can solve P0082 error and can be avoided to return
with proper diagnosis.
- ECM/PCM replacement
- Wiring harness replacement or repairing
- Solving connection issues in relation to
the circuit
- Replacement of the bank 2 intake valve control solenoid
Easy Diagnosis Of Engine Error OBD Code P0082
Use
a DVOM to diagnose this OBD code problem. Pay attention to the circuit between
the ECM and the VVT solenoid valve, as well as the solenoid valve itself.
- Take
the help of a qualified technician to use a scan tool and confirm whether P0082
is present.
- Find
and freeze frame data with the code. Then, clear the code.
- Take
the vehicle on a test drive under the same conditions.
- If
the code reappears, perform a visual inspection of the solenoid circuit and its
wiring.
- If
the wiring is okay, the sensor itself will be tested to confirm operation.
- If
the solenoid is functioning properly, the technician must check the Engine
Control Unit (ECU) for any faults and damages.
- If
all the components are working properly, check for faults in the PCM and
replace or reprogram according to the situation.
Common Mistakes When Diagnosing The P0082 Code
It is important to inspect all the components properly before directly jumping to the PCM or the solenoid for the diagnosis. This way you can avoid the OBD error from reappearing as well as save on future costs as repairs of faults in the wirings are much cheaper that replacing a perfectly healthy sensor or PCM without knowing the main reason of the problem.
- Sensor
solenoid circuit not inspected properly
- Not
checking for damaged connections to the solenoid circuit. Thus, proper
diagnosis is necessary in correct order to properly diagnose OBD code P0082
error.
