Cam sensor bank 2?

There are a total of 4 sensors. Three of them are accessible without a lot of work, the last one is a pain. The right and left intake sensors are out in the open, the right hand exhaust is as well. The left hand exhaust sensor is not fun as you need to remove the transfer case to get room enough to get the sensor out.

Both RH and LH intake Camshaft Position (CMP) sensors and RH exhaust CMP sensor

Disconnect the Camshaft Position (CMP) sensor electrical connector.
Remove the bolt and the CMP sensor.
LH exhaust Camshaft Position (CMP) sensor

Position the vehicle on a hoist.
If equipped with 4 wheel drive, remove the transfer case.
If equipped, remove the 2 bolts and the LH heat shield from the rear of the LH cylinder head.
Disconnect the LH CMP sensor electrical connector.
Disconnect the LH HO2S and the LH CMS electrical connectors, and remove the pushpins from the fuel line bracket.
Position the LH HO2S and the LH CMS harness from the top of the transmission
Remove the fuel line bracket bolt from the left side of the transmission and position the fuel lines and bracket aside.

Remove the CMP sensor bolt.
NOTE Make sure the transmission jack contacts the outer ribs of the transmission fluid pan.

2 wheel drive vehicles, position a suitable high-lift transmission jack under the transmission and remove the 2 transmission support insulator nuts. All vehicles, raise the transmission until the CMP sensor can be removed.
Remove the CMP sensor.
