Question about 2003 Nissan Altima
I have replaced these 2 sensors but after running around for 150 miles the light came back on with crankshaft position sensor again.
MAke sure you replaced the right sensor and it's the proper design.(If you bought a generic part, it;s probably the wrong thing) I replaced my cam and crank sensors with the generic ones from AutoZone and they had no effect. Took it to Nissan, they replaced both at my expense, AND REPROGRAMMED THE ECU. That fixed that problem SES light hasn;t come on in 6 months....Fingers crossed

Ignition coil driver module
Crankshaft position (CKP) sensor
Now which part do you want to replace ?
Cap and rotor
Camshaft position sensor
Gear drive and shaft
The camshaft drives the distributor shaft which rotates providing a spark to the correct cylinder by way of the cap and rotor. The camshaft position (CMP) sensor functions much like the crankshaft sensor previously described but provides only a 1x signal to the VCM. That is, for every 2 rotations of the crankshaft, there is 1 rotation of the camshaft. Note that the camshaft position sensor will not affect driveability. The sole purpose of the camshaft position sensor is to provide the VCM with the necessary information for the misfire diagnostic trouble codes (DTCs).
