Turbocharger/supercharger boost sensor B circuit high

P0240 Turbocharger Boost Sensor B Circuit Range/Performance

Diagnostic Test Code (DTC) P0046 is defined by SAE J2012 as "Turbocharger/Supercharger Boost Control "A" Circuit Range/Performance".

Please note that this is a CIRCUIT code. This means that the electrical circuit for your boost control is not operating within its designed "window of operation". The circuit must be properly diagnosed to determine the actual CAUSE of this code setting.

Specific vehicle/circuit information, as well as proper testing equipment and techniques will be required.

P0029 - Exhaust Valve Control Solenoid Circuit Range/Performance Bank 2
Causes:
- Dirty engine oil
- Low engine oil level
- Exhaust valve control solenoid circuit open or shorted
- Exhaust valve control solenoid circuit poor electrical connection
- Faulty exhaust valve control solenoid

Solutions:
- Change oil
- Replace exhaust valve control solenoid

P0047 - Turbocharger/Supercharger Boost Control A Circuit Low
This vehicle is not equipped with a turbocharger or supercharger if it is a 1994.

P0137 - o2 Sensor Circuit Low Voltage Bank 1 Sensor 2
Causes:
- Sensor circuit harness or connectors is open or shorted
- Rear heated oxygen sensor Bank 1 may be faulty
- Fuel pressure may be faulty
- Fuel injector may be faulty
- Intake air leaks

Solution:
Replacing the O2 Sensor 2 usually takes care of the problem.

P0107 - Manifold Absolute Pressure/Barometric Pressure Circuit Low Input
Causes:
- Damage harness or connectors
- MAP sensor circuit is open or shorted
- MAP sensor
- Damaged PCM or ECM

Solutions:
- If damage, repair MAP sensor harness or connector
- Replace MAP sensor
- Replace PCM or ECM

P0101 Mass or Volume Air Flow Circuit Range/Performance Problem

i would start, given these codes, to look around the air duct assembly for signs of cracks or disconnected hoses resulting in a vacuum leak.

Hello, It should actually be an oil sending unit, and is located on the back of the intake manifold to the left of the distributor. *The P0523 is Oil Pressure Sending Unit Voltage too high *P1693 Generic fault indicating a fault in the bus or PCM/ECM interface *P1682 - I can't find this code Anyways, I will post here all the error codes for future reference.
