Fuel tank pressure sensor - 1/8/2008 6:12:20 PM

OBD Code - P0452

Fuel tank pressure sensor low voltage. I just replaced the fuel pump. I double checked my connections on the new wire harness before I put the tank back up. Now it is having trouble starting sometimes. Sometimes it takes three or four seconds to fire and other times it fires right up. I have a hunch that one of the fuel lines might be pinched. Where is the senor located and how do I check it. Any ideas.

The Fuel Tank Pressure Sensor is on top of the fuel pump module.
Check and make sure that you plugged it back in or for any damage.
If all looks good then replace it.
