WE ARE HAVING PROBLEM FINDING DIAGNOSTIC PROCEDURE FOR CADILLAC DIVILLE WITH DTCs P0029,P0047,P0137 and P0107


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

I have a 2002 Pontiac GTP.I have noticed today on the Interstate that the booster is not performing when i give gas to pass somebody,any idea what the problem could be?


SCAN VECHICLE FOR ANY SUPERCHARGER BOOST SOLENOID FAULT CODES.AND CHECK FOR LOOSE OR BROKEN VACUUM LINES GOING TO SUPERCHARGER BOOST SOLENOID THAT WILL CAUSE NO BOOST PROBLEMS.

Turbo/supercharger under boost


Turbocharger under boost problem:
The car goes in "limp mode"!!!
After scan the EDC-15P engine control unit with a VAG or KTS -BOSCH diagnosis tool you will find this DTC - Fault code: P1557-Turbo Boost pressure control exceeded
1. Engine stopped and ignition switch off. Check all pneumatic connections and hoses between turbocharger actuator = pressure unit for boost-pressure control, boost-pressure control solenoid valve, vacuum reservoir, EGR control solenoid valve, intake-manifold flap solenoid valve, EGR valve with throttle - part of intake manifold. Also the vacuum connection between tandem pump and brake booster. If you find something wrong replace parts. If not go to step 2.
2. Extract the hose of the turbocharger actuator = pressure unit for boost-pressure control part of turbocharger. Instead of the original hose you must place another 1 meter long hose with the same inside diameter, and then you check to inspire yourself the air from the other one extremity of this hose. The mechanical connecting rod of the turbocharger actuator must have a smooth and whole motion. If you can do that with your mouth, then you must replace the boost-pressure control solenoid valve. If you can not reach this with your mouth, then you go to step 3.
3. This is the most difficult work. The problem is that the soot particles deposits inside the turbocharger plugging the variable nozzle geometry mechanism = adjustable vanes of the turbine. If the turbocharger actuator is not able to adjust the turbine vanes the charge air pressure increase too much and ECU (engine control unit) go in "limp mode" = engine protection software. As a result the "limp mode" engine still running until you turn the engine off (ignition switch off) and back on when the "limp mode" is deactivated, but the fault still remain in ECU memory!
4. You must be able to extract the turbo from the engine and then to disassemble the turbocharger, clean inside adjustable vanes mechanism and refit all.

How to repair a supercharger


Fig. 1: Supercharger assembly and related parts 84303024.gif

REMOVAL & INSTALLATION
  1. Disconnect the negative battery cable.
  2. Remove the accessory drive belt from the supercharger pulley.
  3. Relieve the fuel pressure and remove the fuel injector sight shield.
  4. Disconnect the fuel pipes from the fuel rail and vacuum hose at the pressure regulator.
  5. Disconnect the electrical connectors from the fuel injectors and remove the fuel rail mounting bolts. Remove the fuel rail with the injectors intact.
  6. Disconnect the electrical connectors at the IAC, TPS, MAF, EGR and boost control solenoid. Lay the wiring harness aside.
  7. Remove the air intake duct and remove the EGR pipe from the supercharger.
  8. Disconnect the throttle cable and the cruise control cable. Remove the cable bracket.
  9. Remove the tensioner bracket to supercharger mounting stud.
  10. Remove the supercharger to intake manifold bolts, remove the supercharger from the intake manifold. Remove the supercharger gasket and coolant passage O-rings. To install:
  11. Replace the oil passage O-rings and the supercharger gasket.
  12. Install the supercharger and bolts. Install the tensioner bracket-to-supercharger bolt. Tighten the bolts to 19 ft. lbs. (26 Nm).
  13. Install the cable bracket and connect the throttle and cruise control cables.
  14. Connect the EGR pipe to the supercharger and install the air intake duct.
  15. Connect the electrical connectors to the IAC, TPS, MAF, EGR and boost control solenoid.
  16. Install the fuel rail and bolts and tighten the bolts to 15 ft. lbs. (24 Nm).
  17. Connect the connectors to the fuel injectors and the vacuum hoses at the pressure regulator.
  18. Connect the fuel pipes to the fuel rail and install the fuel injector sight shield.
  19. Install the accessory drive belt to the supercharger and connect the negative battery cable.

I have a 2002 Grand Prix GTP and i am having trouble with the supercharger. Most times only getting 1/2 boost on the guage and it runs like a regular 3.8l - the supercharger will ocasionally kick in but...


Check the vaccuum lines to the super charger boost control valve located on the back of the supercharger closest to the air cleaner opposite the pully. If you are not getting vaccuum to the boost control colenoide follow the vaccuum hoses back to the boost control switch and check for engine vaccuum at the switch.
