C0720 Hyundai Sonata 7 OBD Code

OBD/2 C0720 error code description and symptoms.

The Transmission Fluid Pressure Switch allows the engine's control module (PCM) or Transmission Control Module (TCM) to use hydraulic fluid to engage the clutches in the transmission to allow for smoother shifting while driving. If the PCM or TCM detects an issue with the hydraulic clutch or the pressure switch, the PCM or TCM will set code C0720

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code C0720, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code C0720 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

C0720 Hyundai Sonata 7 Error Code Repair Process :

OBD C0720 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 rescu/vems input circuit short to battery, 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 C0720 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 C0720 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 Hyundai Sonata 7 C0720 OBD2 Code

A common cause of code C0720 is the failure of RESCU/VEMS Input Circuit Short to Battery, but there are several other possible causes as well, such as ;

Continuous oil flow to the VCT piston chamber
EVAP canister or fuel tank leaks
Intake air leaks
Oil flow restriction in the oil passages or the variable camshaft timing (VCT) valve body

C0720 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.
