My buddy has a truck that threw these codes:

P1492 - APLSOL Solenoid Circuit Malfunction

P1693 - Turbo Charge Control Circuit Malfunction

Its an '01 24v with no programmer.

The wastegate is blocked off at the compressor.

Only mods are injectors.

What do these codes mean beyond what its telling me?

What part is bad?

 

First off.....here are the correct code definitions.....

P1693-DTC DETECTED IN PCM
P1492-AMBIENT/BATT TEMP SEN VOLTS TOO HIGH

Symptom:
P1492-AMBIENT/BATT TEMP SEN VOLTS TOO HIGH
When Monitored and Set Condition:
P1492-AMBIENT/BATT TEMP SEN VOLTS TOO HIGH
When Monitored: With the ignition key on.
Set Condition: The PCM senses the voltage from the AMBIENT/BATT temperature
sensor to be above 4.9 volts for 3 seconds.
POSSIBLE CAUSES
SENSOR GROUND CIRCUIT OPEN
AMBIENT/BATT SIGNAL CIRCUIT OPEN
AMBIENT/BATT SIGNAL CIRCUIT SHORTED TO VOLTAGE
AMBIENT/BATT TEMPERATURE SENSOR
PCM
WIRING HARNESS INTERMITTENT
TEST ACTION APPLICABILITY
1 Turn the ignition on.
With the DRBIIIt, read DTC’s.
Is the DTC Good Trip Counter displayed and equal to zero for P1492?
All
Yes ® Go To 2
No ® Go To 7
2 Turn the ignition off.
Disconnect the AMBIENT/BATT Temperature Sensor harness connector.
Measure the resistance between ground and the Sensor Ground circuit in the
AMBIENT/BATT Temperature Sensor harness connector.
Is the resistance below 5.0 ohms?
All
No ® Repair the Sensor Ground circuit for an open.
Perform POWERTRAIN VERIFICATION TEST VER - 3.
Yes ® Go To 3
3 Turn the ignition off.
Disconnect the AMBIENT/BATT harness connector.
Disconnect the PCM harness connector(s).
Measure the resistance of the AMBIENT/BATT Signal circuit between the
AMBIENT/BATT harness connector and the PCM harness connector.
Is the resistance below 5.0 ohms?
All
No ® Repair the AMBIENT/BATT Signal circuit for an open.
Perform POWERTRAIN VERIFICATION TEST VER - 3.
Yes ® Go To 4

CHARGING





Symptom:
P1693-DTC DETECTED IN PCM
POSSIBLE CAUSES
DTC DETECTED IN THE PCM
TEST ACTION APPLICABILITY
1 With the DRBIIIt, erase DTC stored in the ECM.
View repair.
All
Repair
With the DRBIIIt, read and repair the stored DTC’s in the PCM.
Perform POWERTRAIN VERIFICATION TEST VER - 5 (DIESEL).
