Engine Light Question????

I have a 2000 Honda Accord EX V6 . My engine light was on so,I went to AutoZone to get a diagnostic check and the codes they came of with are: (P1491 and P0116). Could anyone tell me what do these codes mean and how to fix the problem myself or should I go to a dealer?


Thanks for any help and/or advice,

Just unplug the batterie and then plug it back in it should work

Just unplug the batterie and then plug it back in it should workthis is not a problem solving advice, check engine light will come back on in few days.



P1491 is EGR Valve Insufficient Lift. to solve this problem go to dealer they will fix it, EGR system covered by 8year/80,000ml warranty.

P0116 is Electronic Coolant Temperature Sensor Range/Performance Problem. this could be loose wiring on sensor, check wire connections near thermostat housing, or you can ask dealer to look at this problem while you there taking care EGR problem.

this is copy from haynes manual on how to do diagnostics and reset ECU.
