I just had both my belts changed on a 2004 Infiniti G35 Automatic and as I was driving home my VFD, SLIP, and CHECK ENGINE lights popped on. I was able to drive it home without any loss of power, however when I got home and restarted the car all three lights persisted and my car died while idling even kicking the battery light on. I'm assuming maybe this is just an electrical/computer issue and just restarting the engine will clear the thrown codes/lights. Well... I waited for 30 minutes or so for the vehicle to cool down, and now i'm just getting a check engine light... Keep in mind none of these lights were on before I had both belts changed. The car was put on a lift to change the belts. Anyways, Just wondering if anyone can help me out- or will I need to visit someone with a code reader?

 

We can't read those codes for you, plug in an OBD2 scanner and see what the ECM says is wrong.

First thing I would check is the routing of the belt to make sure they didn't screw it up somehow.

 

I assumed the original issue was due to a loose power steering belt. Now i'm thinking it could be a sensor issue mentioned above.

 

I checked and the belt routing looks fine from what I can tell. I'll give update on what specific codes I get. I had both cam sensors replaced maybe 3 years ago- odd they would go out again. Both sensors were oem.
