How to fix a p1599 and a p1640 on my 2001 Saturn lw200


DTC P1599 will set if the PCM has detected an engine stall condition when:
?€¢
The engine is in run mode.


?€¢
Ignition voltage is present on circuit 839.


?€¢
The CKP signal at PCM is NOT detected.

DTC P1599 is a type D DTC
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+ !

Po75 code


Hi there:
This DTC P0750 refet at Shift Solenoid A Malfunction which means it could be PCM driver, wiring to and from the PCM to shift solenoid A or the solenoid itself. if the circuit was shorted you would have no reverse, if it's open you will have no 4th gear, so from this it would seem you have an open ckt. when you lockout o/d, then it has to stay in 3rd, which is why you can keep driving without it going into neutral on you. check your main harness plug in to the trans for any corrosion, wiring chafes etc. if you had a wiring diagram you could check resistance of the solenoid, it should be between 10 and 25 ohms, if you don't feel comfortable doing this, take it to a dealer.


Hope this helps.

Error code p 0441


P0441 Evaporative Emission Control System Incorrect Purge Flow OBD-II Trouble Code Technical Description Evaporative Emission Control System Incorrect Purge Flow
What does that mean? This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system
. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
EVAP emission canister purge is contolled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank into the engine to be burned, rather than be vented to atmosphere. A vacuum switch is used to detect when flow exists. If the PCM commands purge and sees that the switch is closed (indicating no detected purge flow) P0441 is set.
copyscape.gif Symptoms Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light.
Causes A code P0441 could mean one or more of the following has happened:
  • Bad vacuum switch
  • Broken or damaged EVAP line or canister
  • Open in PCM purge command circuit
  • Open or short in Voltage feed circuit to Purge Solenoid
  • Faulty purge solenoid
  • Restriction in EVAP solenoid, line or canister
  • Corrosion or resistance in purge connector
  • Bad PCM
Possible Solutions With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
  • Common Chrysler fix - Replace Leak Detection Pump / LDP
  • Repair damaged EVAP lines or canister
  • Repair open or short in voltage feed circuit to Purge Solenoid
  • Repair open in PCM purge command circuit
  • Replace purge Solenoid
  • Replace vacuum switch
  • Repair restriction in Evap line or canister or soleniod
  • Repair resistance in purge connector
  • Replace PCM
