I have a 2004 350z coupe, its auto. Have 151k miles. Today in the morning. I was driving and my check engine light went on, and also a slip light and my traction control off light came on. I was reading and people say its the speed sensor/abs sensor? Idk? It takes longer to crank up, and in one ocation..it turned off on me. And lost acceleration. What can It be? I have 18' wheels after market. No mods on engine. All stock. Help me

 

The problem is the crankshaft sensor(s) and/or the camshaft sensor(s).

It's an easy fix. --Spike

 

Crankshaft sensor?????

 

@spike how sure are you its the crankshaft sensor? I looked it up and it seems about right. Its 30 bucks on autozone

 

Spike is right. It is prolly one of those two things. If you check your OBD code you would prolly have a P0024 code which is the code for vvt camshaft or something like that. I went through that problem last month (minus the slip light and traction control light) where I had the cheque engine light on and sudden loss of acceleration and then engine stall. Got the cam shaft sensors changed and vvt solenoids cleaned up.

 

Check code.

the camshaft sensor should be P0340. That is bank 1 or passenger side.
P0345 is the driver side.

These is a notorious issue for 350z. Just buy a new sensor and replaced it.

It's funny how we get this on the same timing, my Z has 154K and also throws the same problem. I couldnt start the car at one time and I have been getting SES light.

 

If it takes a while to turn over, I would also check your battery and make sure it's not getting weak. If the battery + alternator is kicking the bucket, weird things will happen to.

A simple volt meter check will tell you if your alternator/battery are in good shape.

I'm betting crankshaft rather than cam position sensor. When my cam position sensor went, I didn't lose power so much as it was hard to start when warm. but as mentioned, GET THE CODE READ. ALWAYS the first place to start instead of simply throwing money at it.
