Plug in a code reader, see what it reads.

 

I just put the key on and off for 3 times, and saw the code is p1684. I don't know what is for

 

What is error code p 1684?
P 1684 is "Battery disconnected within last 50 starts"
What is error code p 168...

 

Did you get a p0340 also?

 

P0340
Camshaft position sensor circuit
Most likely cause : Camshaft position sensor failed.
-----------------------------------
P1684
means the battery was disconnected(or had been drained to a low voltage)

 

Because, no check engine light on,so i do not see another code .

 

FWIW 99-01 speed sensors prone to failure, 02 and up solenoid pack suspect. Have the codes read with a code reader. Trans codes other than p0700 do not show up with the "key dance"
