Nice answer.
For any vehicle, try looking up your codes here: http://www.obd-codes.com/trouble_codes/
P0340 Camshaft position sensor circuit P0340 (M) No Cam Signal At PCM No fuel sync.
There is no error code PO329 for a Nissan Altima. The closest codes for this would be P0335 which is the CKP Sensor or P0340 which is the CMP Sensor, Detectable Or Undetectable Circuit.
Trouble code P0340 means:Camshaft position sensor circuit malfunction
Trouble code P0340 means: Camshaft Position Sensor A Circuit (Bank 1 or single sensor)
Codes P0344 and P0340 indicate issues with the camshaft position sensor or its circuit. To fix these codes, first, check the camshaft position sensor and its wiring for any damage, corrosion, or loose connections. If the sensor appears faulty, replace it. Additionally, inspect the related components and clear the codes to see if they reappear after repairs.
P0455 and P0452 have to do with fuel vapor leaks, will not cause a starting problem. P0340 is a cam sensor code. You need to diagnose for a failed cam sensor.
Go to www.banzai-racing.com , it will tell you how to get the error codes and what they are.
55 code is not an error code, it signals end of codes. If no other codes preceded it, you have no error codes.

The Check Engine Light should be on if the sensor is faulty. The car may or may not hesitate, stall, or accelerate poorly. To read the engine error codes, cycle the ignition key from "off" to "on" three times: Turn the iginition key to the "on" position where the check engine light comes on but do not start the car. Turn the ignition key to off, then on, off, and on again and leave the key there. The odometer will read out any error codes. P0340 and P0344 are trouble codes for the camshaft position sensor.
Visit Gamefaqs.com and go to the cheats/codes section for MMBN3. You'll get error codes, numberman codes, ex codes, SHRINK codes (those are helpful) and more.
Error codes are codes that tell when a computer or car is having problems and a rough idea as to what the are. Beyond that, we will need a more specific question.
