How do I replace a camshaft position sensor on a Nissan Maxima? Got a P0340 error code

SOURCE: error code P0340

lionelloopho: P0340 is a Cylinder signal not getting to the ECM, momentarily while the engine is being cranked.
According to Nissan's diagnostic chart, the recommend checking the following: Harness connectors for the cam positioning sensor,
The sensor it self, The starter, for excessive draw.
The battery for weakness.
Nissan did have a service bulletin out on hard cranking problems.
The symptoms include difficult starting ans spark knock (very sharp rattling sound)
The bulletin reference number is: NTB95-090 You can check with Nissan because the solution warrants the replacement of the ECM.
You may have to tell a little white lie and tell them you have been living with the problem for quite a while because no one has been able to solve the problem and you have just now heard of this bulletin.
Good Luck and let me know how you make out, I'm pretty sure this is the solution.
