DTC P0340 Camshaft Position (CMP) Sensor Circuit Malfunction
Thursday, March 17, 2011 4:39 PM
I have this code throwing on my 2003 Pointiac Sunfire. Just purchased car today so as of yet I have no mechanical knowledge of them. If anyone would like to help me I would definitely appreciate it. Another code thrown is P0171, which is "Running too lean" and if I'm correct is because of this sensor... Dealer said they would fix it tomorrow if I knew what was wrong with it (buy here pay here grrr).

How much should I expect to pay to get this fixed? Where is this sensor? Thanks in advance and I look forward to posting here,hopefully under better circumstances. Only reason I got this car is because a Durango pulled out in front of me Monday morning and totaled my Neon

I've been doing some research and cannot find ANY information on this...

Is there something that I don't know? Could this be a distributor problem?

I can't find any information on a Camshaft Position Sensor for a 2003. Is there even one in this engine?

What else might cause this problem? I really don't want to have to take this to a dealer seeing as I won't have to pay much of anything at all since I just bought it.

I don't understand why nobody has responded to this. It's the only post that hasn't been answered and it's been up for like three days. The CEL is only on sometimes. Half the time I start my car and it's not on. Does anyone know anything about this?

The eco does not have a cam sensor but try swapping spark plugs and take a look at your coils.
