| The EHA (Electro-Hydraulic-Actuator) is an electrical valve that controls the pressure on fuel distributor. The duty cycle of the EHA valve is determined by the O2 sensor. The EHA valve is only used on vehicles with the KE-JETRONIC fuel injection system. | The EHA (Electro-Hydraulic-Actuator) is an electrical valve that controls the pressure on fuel distributor.

| There are 2 small o-rings that seal the EHA valve to the fuel distributor. As these wear out from old age, fuel pressure may leak from this area and cause issues such as difficulty starting, incorrect fuel mixtures, etc... These can be easily sourced online by searching **2430210041** online and replaced. More often than not, these o-rings go bad before the EHA itself goes bad. | There are 2 small o-rings that seal the EHA valve to the fuel distributor.
