Driver problem

[coolflames]

I am having a problem with a DTC. First it was a 1665 and the description was "driver 3 line 5" and recently I got another one with description "driver 4 line 6". What is this? I can't find any information about these DTC's.

Wrong! 1665 is "driver 3 line 5" and 1676 is "driver 4 line 6". Is that the injector drivers?

You need to indicate what year, make, and model you are working on. John F is right that P1665 is EVAP on the L67 GTP cars. Now you might very well have a different definition in your case. I have seen the Driver 3 and Driver 4 errors, and have read that they are specific defined lines by GM per PCM code.

And it is not the injectors drivers. I thought it was too the first time I saw them couple years ago.

Sorry, I thought all DTC's are the same for all PCM's. Didn't mean to offend anyone, just trying to get that problem solved .My PCM is a 1998 GTP.

Well what I have found out is this may be a DTC bug. The 1998 book defines P1665 as EVAP Vent Solenoid Control Circuit.

As you can see in this screenshot that HPT defines it different.



P0446 is defined as EVAP Canister Vent Blocked.

Someone at HPT needs to change this in the database definitions.

P1665 has been modified.
