I have an automatic 2002 civic ex and the engine check light came on. I got the code read at an auto shop and it said "high vehicle speed observed in park" what the hell does that mean and how do I fix it?

 

What exatally was the code P____? Ex (P1456)

 

never heard of that problem, I'm curious what the code is too.


either way, vehicle could have been a one time thing. so reset the ecu.


under the hood, go to fuse #6 pull it out for 10-20 seconds and the ecu will reset. see if that gets rid of the ight first


then tell us if it's still on and same code or not.

 

maybe you drove with your ebrake up or something and you messed up your speed sensor? either way, reset your ecu, hopefully it'll go away.

 

what is the P1456

I'l just state it since the thread starter wont say what his code is.

p1456 -EVAP Emission Control System Leak Detected (Fuel Tank System)

 

sorry i'll post up the code later on. i'm currently on vacation

 

did you previously fill up with gas ? do you tighten the fuel cap when u put it back on ?

 

the P1456 happened to my car.. never fixed it .. but i tighten the gas cap.. still wouldn't work. but oh well i sold it..

 

That was just an example...

 

nope...completely wrong buddy. the codes i have are P1706 (High vehicle speed observed in park) and P0113 (the PCM has determined that air input from the intake air temperature sensor is higher than expected for the current engine operating conditions). Can someone help?

 

ok the 1706 is Open in Transmission Range Switch Circuit

the 0113 is your IAT

I've had that problem too.

first cheack the wires from the PCM to the IAT and make sure none are broken or open to make a short. shouldn't be open but rather broken. that's what mine was, if it's not that and all the connections are good then tell me theres another thing you can do.


the 1706 it is probably the switch, it might need replaced or there might be a short.


do this, reset the ecu. using fuse #6
see if the light is gone.

if it is still there start car drive to about 40 then stop and turn off car and then do it again.

if light is still on then reset ecu again with fuse 6 and see if the light goes away.


if it doesn't go away then prolly have to go to the dealer and it will be very expensive sense they will test the wires in A LOT of places.
