P0B33 Mercedes C 32 OBD Code

OBD/2 P0B33 error code description and symptoms.

Variable Cam Timing Over-advanced (Bank 1) The comprehensive component monitor (CCM) monitors the VCT position for an over-advanced camshaft timing.
The test fails when the camshaft timing exceeds a maximum calibrated value or remains in an advanced position. Cam timing improperly set No oil flow to the VCT piston chamber Low oil pressure VCT solenoid valve stuck closed Camshaft advance mechanism binding (VCT unit) P0B33 DTC is a check of the VCT unit.

In most cases, the TCM is integrated into a single housing with the PCM. Nevertheless, the section of the module which controls (automatic) transmission function may be powered up separately. In any case, the TCM is typically powered using switched (only present with the ignition switch in the ON, start, or run position) voltage. This circuit is normally equipped with a fuse, fusible link, and/or a relay. Frequently, the PCM and TCM are powered using the same relay albeit by separate circuits. Access to a reliable vehicle information source will yield necessary details of the TCM power circuit for the specific vehicle in question.

The rule of P0B33 code when it comes to emissions-related vehicle repair is that any modification that changes the vehicle from a certified configuration to a non-certified configuration is considered tampering: this applies to both vehicle owners and repair facilities and is, therefore, a Federal offense. Replacing a catalyst with a straight pipe is one traditional example of pwm input circuit failure. Likewise, overriding the OBD P0B33 error in system through the use of high-tech defeat devices or non-certified computer chips, for example, would also be considered tampering. The OBD system may, however, be repaired back to its original certified configuration with certified performance chips or appropriate aftermarket parts.

Common Causes of Mercedes C 32 P0B33 OBD2 Code

A common cause of code P0B33 is the failure of PWM Input Circuit Failure, but there are several other possible causes as well, such as ;

Camshaft advance mechanism binding (VCT unit)
Air fuel ratio (A/F) Sensor 1 Bank 1 harness is open or shorted
Intake air leaks
Variable Camshaft Timing solenoid stuck open

P0B33 is a kind of Powertrain Trouble Code
