check engine light-engine knock sensor tripped
i have a 98 Altima, 62,000kms...

I have already:

-replaced spark plugs and wire set,
- distributor cap & rotor
- as well as the mainfold gaskets...

The car seems to run fine but the check engine light is on, and this is what the ECM codes for self diagnostic read:

3 long, 4 short = engine knock sensor and

7 long, 5 short = no definition in my Haynes manual...

I called my dealer, and he says 80% of the time, its 'cause of a loose fuel cap, and to see if the computer resets itself after 10 starts/stops...

Any suggestions? Is it probably a loose fuel cap?

Thanks for your help!

check the connection on the knock sensor and clean/tighten the knock sensor if needed. the thing is, a code 34 is not the type of code to trip the cel. also, a bad knock sensor wont affect the car in a way you can feel, day to day. my guess is the other code is the trouble maker. go to www.batauto.com and see if that code is listed.

Yes, it is a loose gas cap. Happens to me all the time...gotta let it click at least twice when you're closing it


also, you can reset the ECU yourself. No dealer or OBDII computer needed!


I have a 98 Altima GXE that does the same thing
