Error Code P2664: What It Means & What To Do?
OBD Code P2664 - B Rocker Arm Actuator Control Circuit High Bank 2
The trouble code P2664 can be explained as B Rocker Arm Actuator
Control Circuit High Bank 2. This diagnostic fault code is a generic powertrain
code, which means that it would apply to the OBD-II equipped vehicles. The
specific repair steps can vary as it depends upon the vehicle make and model.
One thing which you must keep in mind that its symptoms as well as causes would
surely vary as it depends upon a number of things. The B rocker arm actuator
control circuit is being monitored by the engine control module. This trouble
code would be set by the ECM when the B rocker arm actuator control circuit
would not be as per the specifications set by the manufacturer.

Replace/Repair These Parts To Fix OBD Code P2664
- Fuel Injector -
Bad fuel injectors can cause starting issues, poor idles and affected
performance. Thus, the replacements are in order. Buy new fuel injectors now!
- Engine Control
Module - ECM faults are rare but can be a big
problem as faulty ECM will cause wrong vehicle operations and can also result
in wrong OBD codes getting stored in the system which can also cause
misdiagnosis. Thus, replace faulty ECM components now!
- Electronic Control
Unit - The ECU coordinates with the
temperature sensor to control the blower fan for keeping the battery
temperatures under control. So, replace faulty ECU components now!
- Powertrain Control Module - Check for PCM error which might be due to circuit faults that might require complete replacement and reprogramming. Replace it now!
- Diagnostic Tool - In order to detect the error, one
needs high grade diagnostic tools. Visit us today to grab amazing deals.

Easy Diagnosis Of Engine Error OBD Code P2664
Here are some steps which you should follow in order to diagnose this fault code:
Carefully examine the crankshaft and camshaft positions using electromagnetic sensors. A proper diagnosis should begin with making sure that all engine timing indicators are properly aligned. After that, test belt or chain deflection using manufacturer’s specifications. VVT or VCT solenoids and circuitry is to be tested if timing components prove to be properly aligned and in good working order. Check for electrical wiring and connectors as they are more prone to fail than sensors, especially where oil or other corrosive fluids are present. An OBD-II scanner (or code reader), a digital volt/ohmmeter, and an oscilloscope can be used to diagnose this error. Repair or replace damaged, disconnected, shorted, or corroded wiring, connectors, and components as necessary. Always retest the system after repairs are completed to ensure success. If all system wiring, connectors, and components (Including fuses) appear to be in normal working order, connect the scanner (or code reader) to the diagnostic connector and record all stored codes and freeze frame data.
Common Mistakes When Diagnosing The P2664 Code
- Non performance of the powertrain control module
- Failure in the variable valve lift controller assembly
- Issues related to the wiring
