Cat C-7 Code

broken wire, corroded connector ore bad solenoid..... grab your DVOM and find the problem! CAT Sis will help with diagram!

 

0032-05 Turbo Wastegate Solenoid current low

SMCS - 5479-038


Conditions Which Generate This Code:

The Engine Control Module (ECM) detects the following conditions:

• The ECM detects a low current condition (open circuit) in the circuit for the wastegate solenoid for more than 0.12 seconds.
• Battery voltage is above 9 V.
• Desired current must be more than 0.2 amp.

System Response:
The ECM will log the diagnostic code and the ECM will trigger a snapshot. The check engine lamp will turn on once the diagnostic code has been active for one minute. After the derate has been activated Caterpillar Electronic Technician (ET) will indicate "Turbo Protection Derate Active".
The engine will be derated while this diagnostic code is active. This diagnostic code indicates a problem with the circuit for the wastegate solenoid.


System Operation Description:
This procedure covers the following diagnostic codes. These diagnostic codes indicate that an electrical problem is occurring with the wastegate control solenoid:

• 32-05 Turbo Wastegate Solenoid current low
• 32-06 Turbo Wastegate Solenoid current high
• 32-11 Turbo Wastegate Solenoid current mismatch

If a mechanical problem occurs with the wastegate control valve or with the wastegate valve, the following diagnostic codes will become logged:

• 102-01 Low Boost Pressure
• 102-02 Boost Pressure signal erratic
• 102-07 Boost Pressure not responding

This engine utilizes a wastegate control valve that is electronically controlled in order to precisely regulate the boost pressure. The Engine Control Module (ECM) monitors the signal from the boost pressure sensor in order to determine the boost pressure in the intake manifold. The ECM uses this information and other information that is related to the current power demand and the current engine operating conditions in order to determine the optimum position of the wastegate valve at the turbocharger. The turbocharger's wastegate valve regulates the amount of exhaust gas that is allowed to bypass the turbine wheel of the turbocharger. This allows the ECM to control the speed of the turbocharger and the boost pressure.

Boost pressure from the intake manifold is diverted through wastegate pressure line (3) to wastegate actuator (4) that is mounted on the turbocharger. The wastegate actuator contains a diaphragm that is used to actuate the control rod assembly (5) for the wastegate valve. As the pressure in the wastegate actuator builds the control rod assembly is extended. This causes the wastegate valve to open the bypass passage that is internal to the turbocharger housing. Drain orifice (6) is used to allow line pressure to escape as the actuator's diaphragm is allowed to relax.
Note: Attempting to defeat the wastegate could cause the engine to be derated. Note: The ECM exercises the wastegate control valve during periods of extended engine idle. The wastegate control solenoid is energized periodically if an extended period of low engine idle is detected by the ECM. This is normal. Do not troubleshoot the wastegate solenoid for this reason.
This is some info for the engine WAX09594 pasted from CAT SIS.

 

I tried just WAX without numbers and it gives the same information.
32-05 Turbo Wastegate Solenoid current low 32-06 Turbo Wastegate Solenoid current hig 32-11 Turbo Wastegate Solenoid current mismatch

 

Flash it back to stock hp, its got the wrong file in it.

 

Some WAX did not have a waist gate solenoid. On the left hand side of the engine where the solenoid should be is the harness plug blanked off. Just connect the two wires together and the code will stop coming up.
