Where is the bank 2 camshaft sensor on 2006 gs300 lexus

It is definitely a cam problem. Was your replacement cam sensor OEM Japanese Denso, Made in China or Made in Mexico? Never go cheap on sensors.

DTC P0348 stands for Camshaft Position Sensor "A" Circuit High Bank 2. This code triggers when the signal coming from the CMP sensor located in bank #1 is either missing or inconsistent. The CMP sensor measures the speed and position of the engine's camshaft.

P0348 Code: Camshaft Position Sensor "A" Circuit High Bank 2

..

Replace sensor A bank 2 with an OEM part.

That is a separate fault. P0345 is definitely the Camshaft Position Sensor and should not be related to the transmission. Did you clear the code with a Code Scan Tool?

P0022 A Camshaft Position - Timing Over-Retarded (Bank 2)
P0345 Camshaft Position Sensor circuit malfunction
P0431 Warm-up Catalyst system below efficiency

A bad camshaft sensor or wiring to the the sensor would cause the other two codes. Since P0345 refers to a circuit issue, get the wiring diagram and check the circuit before assuming you have a bad sensor. If the circuit checks out, then consider replacing the sensor. After that, clear the codes and drive to see if they come back.

this is code p0340
P0340 Camshaft Position Sensor Circuit Malfunction and this is p0345
P0345 Camshaft Position Sensor Circuit Malfunction Bank 2 problem can be the sensor --but this is circuit so sensor --wiring -harness --connections etc ---and if your at dealer ask them also about your codes

I am not sure what "slip n tcs" means but on the 2005 nissan maxima the code P0340 is for the camshaft position sensor circit on bank 1, which is in the rear of the engine compartment. Code P0345 is for camshaft position on bank 2, which is in the front of the engine compartment. The images show the Cyl banks and a cam sensor.

P0345 Camshaft Position Sensor A Circuit Malfunction (Bank 2) A code P0345 could mean one or more of the following has happened:

• a wire or connector in the circuit could be grounded/shorted/broken
• the camshaft position sensor may have failed
• the PCM may have failed
• there exists an open circuit
• the crankshaft position sensor may have failed
• • Visually inspect all the wiring and connectors in the circuit
  • Check for continuity in the circuit wiring
  • Check the operation (voltage) of the camshaft position sensor
  • Replace the camshaft position sensor as required
  • Check the crankshaft position circuit as well
  • Replace circuit wiring and/or connectors as required
  • Diagnose/replace the PCM as required

The Camshaft Position Sensor (CMP) on the 4.0L 6cylinder engine is bolted to the top of the oil pump drive shaft assembly. The sensor and drive shaft assembly is located on the right side of the engine near the oil filter.

Hope this help; remember comment and rated this. TY for using Fixya.

The difference between the two is,
P0345--- there's a problem in the camshaft position sensor "A" circuit on bank 2,
P0349--- it's an intermitten problem in the camshaft position sensor "A" circuit on bank 2, which means the problem comes and goes.
