It is behind the timing belt cover and mounted on the oil pump. Right side of engine (looking at the crankshaft pulley)

Camshaft Position SensorRemoval and Installation
Discharge air conditioner and recover refrigerant You may be able to avoid this task if you can just remove the compressor and place it to the side.Disconnect battery ground cable (14301).Using 3/8-inch drive flex-head handle, rotate drive belt tensioner (6B209) and remove drive belt (8620).Remove four bolts securing A/C compressor (19703) to A/C compressor mounting bracket (2882) and set aside.Remove three bolts and A/C compressor mounting bracket with attached power steering
pump (3A674) and set aside.Disconnect engine
control sensor wiring (12A581) from camshaft
position sensor (CMP sensor) (6B288).Remove two bolts and camshaft position sensor from oil pump
Install camshaft position sensor on oil pump. Tighten two screws to 5-7 Nm (45-61 lb-in).
Connect engine control sensor wiring to camshaft position sensor.
Install A/C compressor mounting bracket with assembled power steering pump and hand start upper front bolt (tight hole) then upper rear bolt (slot hole).
Tighten upper front bolt to 40-54 Nm (30-40 lb-ft).
Install and tighten lower front bolt to 40-54 Nm (30-40 lb-ft).
Tighten upper rear bolt to 22-28 Nm (16-21 lb-ft).
Install and tighten lower rear bolt to 40-54 Nm (30-40 lb-ft).
Install A/C compressor and hand-start upper front bolt.
Install and tighten lower front compressor-to-bracket bolt to 22-28 Nm (16-21 lb-ft).
Install and tighten upper rear bolt to 22-28 Nm (16-21 lb-ft).
Install and tighten lower rear compressor-to-bracket bolt to 22-28 Nm (16-21 lb-ft).
Position drive belt. Using flex-head handle, rotate drive belt tensioner and put drive belt in place. Rest tensioner pulley on drive belt to tension.
NOTE: When the battery (10653) has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module (PCM) (12A650) relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.
Connect battery ground cable.
Recharge air conditioning system as outlined in Section 12-00.
