U2222 Porsche 935 OBD Code

OBD/2 U2222 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 U2222, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code U2222 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

U2222 Porsche 935 Error Code Repair Process :

OBD U2222 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 no movement detected after an unlatch during power open, 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 U2222 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 U2222 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 Porsche 935 U2222 OBD2 Code

A common cause of code U2222 is the failure of No Movement Detected After an Unlatch During Power Open, but there are several other possible causes as well, such as ;

• Dirty Oil
• Camshaft Position Sensor harness is open or shorted
• Exhaust tube
• Damaged camshaft position (CMP) sensor

U2222 is a kind of Network Trouble Code U-code indicates that engine communication errors and shows lost communication with engine parts.U-Codes are fairly straight forward, given all of the articles and technical publications that have been written regarding these problematic codes. In most cases, it just comes down to identifying the module that isn't communicating with the other modules on the CAN bus line for whatever reason.
