C278E Packard Cavalier OBD Code

OBD/2 C278E error code description and symptoms.

EGR Flow Insufficient Detected The EGR system is monitored during steady state driving conditions while the EGR is commanded on.
The test fails when the signal from the DPF EGR sensor indicates that EGR flow is less than the desired minimum. Vacuum supply EGR valve stuck closed EGR valve leaks vacuum EGR flow path restricted EGRVR circuit shorted to PWR VREF open to D.P.F. EGR sensor D.P.F. EGR sensor downstream hose off or plugged EGRVR circuit open to PCM VPWR open to EGRVR solenoid D.P.F. EGR sensor hoses both off D.P.F. EGR sensor hoses reversed Damaged EGR orifice tube Damaged EGRVR solenoid Damaged PCM Perform KOER self-test and look for DTC C278E as an indication of a hard fault.

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code C278E, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code C278E on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

C278E Packard Cavalier Error Code Repair Process :

OBD C278E 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 brake pedal input circuit ground short, 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 C278E 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 C278E 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 Packard Cavalier C278E OBD2 Code

A common cause of code C278E is the failure of Brake Pedal Input Circuit Ground Short, but there are several other possible causes as well, such as ;

• Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
• Faulty select solenoid
• Continuous oil flow to the VCT piston chamber
• Faulty Mass Air Flow (MAF) sensor

C278E 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.
