C247F Holden Hk OBD Code

OBD/2 C247F error code description and symptoms.

Catalytic converters must be warm before they can work properly. On a cold start the PCM provides a rich mixture to keep the cold engine running.
All that extra fuel goes into the catalytic converter. But the exhaust isn't very hot, because, ah, the engine is pretty cold. GM has employed several strategies to fire up the catalytic converter quicker and reduce cold start emissions. One way is to use a secondary air pump that pumps outside air directly into the catalytic converter.

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code C247F, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code C247F on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

C247F Holden Hk Error Code Repair Process :

OBD C247F code and tailpipe testing are two different approaches to identify vehicles in need of repair. The OBD system looks for broken or malfunctioning emissions control components and torque converter clutch circuit malfunction, while tailpipe tests sample a vehicle's exhaust to see if it is above or below certain prescribed limits. Given the robust nature of today's emissions control components, it is entirely possible for an individual component to C247F malfunction without leading to an immediate increase in emissions at the tailpipe. In such cases, other components (like the catalyst) can temporarily compensate for the part that is broken however, these other components can only do double duty for so long before they, too, begin to malfunction. In addition, OBD also monitors for C247F and other malfunctions in the fuel system problems that traditional tailpipe tests were not designed to identify. Most state and local areas also include a gas cap pressure test as part of an emission inspection.

Common Causes of Holden Hk C247F OBD2 Code

A common cause of code C247F is the failure of Torque Converter Clutch Circuit Malfunction, but there are several other possible causes as well, such as ;

Dirty Oil
Damaged camshaft position (CMP) sensor
Damaged ECM
Clogged or faulty fuel injector (s)

C247F is a kind of Chassis Trouble Code

Diagnosing chassis noises can be one of the most frustrating problems technicians face. Fortunately, manufacturers have engineered noise, vibration and harshness (NVH) diagnostic techniques and equipment to find the source of the noise.
