DTC P1599 will set if the PCM has detected an engine stall condition when:
DTC P1599 is a type D DTC
?€¢
The engine is in run mode.
?€¢
Ignition voltage is present on circuit 839.
?€¢
The CKP signal at PCM is NOT detected.
The PCM has the ability to set a diagnostic trouble code (DTC) if the engine stalls when the ignition has NOT been turned OFF. This DTC may aid in intermittent diagnosis of a customer complaint of intermittent engine stall. The scan tool Failure Record information can be duplicated under the same stall conditions in an attempt to reproduce the occurrence. Since DTC P1599 is a type D DTC, the PCM will not command the MIL or SERVICE telltale ON. This DTC can set due to driver error. For example, a vehicle equipped with a manual transaxle in which the clutch was released too quickly causing the engine to stall.
DTC P1640 (PCM Output Circuit)
The PCM contains an output driver module (ODM) which controls 7 circuits: A/C relay, air pump relay, EVAP purge solenoid, EVAP vent solenoid, fan control 1, fan control 2, and TCC solenoid. The ODM controls each of these circuits independently by controlling the circuit ground. The ODM monitors the voltage level at each of the 6 circuits into the PCM when the device is being commanded ON or OFF. When the device is commanded OFF, the circuit is not grounded, the voltage level at the PCM should be high (ignition voltage). When the device is commanded ON, the circuit is grounded, the voltage level at the PCM should be low. Each of the 7 drivers in the ODM contains a feedback circuit used to determine if a particular circuit failed, which can be read on the scan tool. DTC P1640 sets when any one of the 7 feedback voltages is low when that device is turned OFF or when any one of the 7 feedback voltages is high when that device is turned ON when the engine is running.
Sounds to me like you have a short on one of these circuits !
To locate an intermittent problem, use the scan tool to command each of the 7 solenoids tied to the ODM circuit ON and OFF independently while monitoring:
A/C RELAY CKT OPEN SHORT TO GND
A/C RELAY CKT SHORT TO VOLTS
OR
AIR PUMP REL. CKT OPEN SHORT TO GND
AIR PUMP REL. CKT SHORT TO VOLTS
OR
EVAP PURGE CKT OPEN SHORT TO GND
EVAP PURGE CKT SHORT TO VOLTS
OR
EVAP VENT CKT OPEN SHORT TO GND
EVAP VENT CKT SHORT TO VOLTS
OR
FC 1 RELAY CKT OPEN SHORT TO GND
FC 1 RELAY CKT SHORT TO VOLTS
OR
FC 2 RELAY CKT OPEN SHORT TO GND
FC 2 RELAY CKT SHORT TO VOLTS
OR
TCC DUTY CYCLE OPEN SHORT TO GND
TCC DUTY CYCLE SHORT TO VOLTS
If IGN 3 fuse is open, A/C RELAY CKT OPEN SHORT TO GND, EVAP VENT CKT OPEN SHORT TO GND, and EVAP PURGE CKT OPEN SHORT TO GND parameters on the scan tool will read YES.
Do you have a DVOM - digital volt ohm meter ? You need to check each wire in the above circuits for a short to ground or B+ !
The only thing that I found was a blown fuse for fan
Which fan , cooling fans or heater fan ? Did you replace the fuse an did it blow again ? Fan has high resistance ,or relay for the fan !
fan control 1, fan control 2
Blown fuse was on fan 2
Replaced fuse did not blow again
Have the codes cleared an see if they come back , if not don't worry about
I cleared codes and I still can't get the car to run
One of those circuits is shorted an causing your problem , it's shorting out the PCM.
Just to let everyone know I had been working on this car for a couple of months and was unable to fix the problem I eventually had to scrap the car after several hundreds of dollars fixing wires and replacing parts with no success of fixing the car even replaced computer thanks for all the help
Did you try an independent ASE certified automotive electric repair shop .It's hard giving advice on here . the only way to find a problem is testing an not replacing parts . Electrical trouble shooting is a challenge at best. An if you have no training it is near impossible .

smell sweet ? could be a heater matrix , check coolant level to confirm this
could be a big job depends how they built the matrix in the dashboard
best of luck

If you mean the lever for turning them on and off you will have to replace the switch assembly

Go autozone.com type in you make and model it will give you the diagram
Testimonial: "I tried Autozone already, and though I put in the car year and model correctly, the diagram they showed me was clearly incorrect. I found my answer through searching the fixya forums a little more thoroughly though, and now have belt replaced, running fine."
