HI friends,
My 2001 Toyota Camry LE the check engine light has come and I took it to Autozone .After checking report told me that error code is PO 402 and EGR insufficent flow.Autozone asked me to pour Seafoam auto marine fleet(which cleans carbon).Now they resetted and now no engine check light and please guide me what to do.
How serious is this error code?
P0402 (EGR insufficent low detected) this is the error I got .Now they resetted .how critical issute this ?do i need to visit the mechanic immdtly?
 
The error code isn't serious and usually doesn't effect how the car runs but might effect gas mileage slightly. The guy at Autozone was probably right the EGR (Exhaust gas re-circulation) valve probably had some carbon in it effecting the gas (air) flow. If the check engine light is off and stays off then it is no longer a problem. Don't worry about it.
