Best Answer

A P0402 indicates that the PCM is seeing voltages higher than expected from the DPFE(Delta Pressure Feedback Exaust) sensor. The DPFE is the EGR position sensor. The high than expected reading could be caused by an EGR valve that is either sticking open, EGR valve that is being held open by the EGR vacuum regulator, or it could be a faulty DPFE sensor.

How do you solve P0402 code check engine light on 98 Accord?

P0402 code on 1998 Accord is related to low performance of the O2 sensor/Cat converter. It simply can be a result of a computer oversensitiveness. You will need to reset the computer in this case. To do this : Start the engine. Rev the engine upto 3000 RPM until the radiator fan comes on ( may take upto 10-15 minutes). Shut off the engine. Start again and hopefully the check engine light should be off if the above case is true. If not the next step would be to replace both O2 sensors. The next thing would be Catalytic converter which is the most expensive bit.
