Default FIXED UPDATE What went wrong real fast daughter with newborn

As many of you know my daughter was having a baby and needed a car so I shipped my car to her in Orlando. She received the car 3 days before delivering the baby.
2 days after having the baby the car has died. She has been able to have someone scan the system and these are the codes that it spit out.

DTC P0740 TCC Enable Solenoid Circuit Electrical
DTC P1655 Evaporative Emission (EVAP) Purge Solenoid Control Circuit
DTC P1675 Evaporative Emission (EVAP) Vent Solenoid Control Circuit

Please, has anyone have any ides what these could mean?
The car was running like a champ and then the next time she started it, it had all these problems. She says the trans will not start off in 1st gear!
And she says the engine runs rough.
She needs this car to get her and the baby to the doctors and whatever so I need to help her.
Please any Ideas what they mean?
I am hoping it is a simple fix like a vacuum leak but I am unsure about the TCC code.

Nick...definately check the vac lines going to the canister. Most likely I'd aim straing under the air box (two 5.5mm screws next to the radiator and push off the accordian and it'* a pull out) theres two small pieces connecting the metal lines. They always go bad. From there..I'd follow the metal line up to the evap purge soleniod and check all vac lines there including the electrical connector. I got this code or something like it when I put my engine cover on and bumped a line. (SC motor it'* right next to the cover)

did you miss-type P1655 to a 1665, or I am I wrong?
If it is 1655 as I stated, is your answer still the same?
and thanks for the reply.....

Bill, I hope it is that easy of a fix, I had the same thoughts as you......

if anyone else has any suggestions please continue to post as this is my only resouce for help and I am at your mercy......

My Apllogy Nick... Dragging dead tired.. I miss typed... That was for the 1655 I went back and changed it..

I do hope its a simple fix
thanks.....as far as a simple fix, so do I......

This is going to get long...but it'* the most info I can give this way
P1655
ircuit Description

Output Driver Modules (ODMs) are used by the PCM to turn on many of the current-driven devices that are needed to control various engine and Transaxle functions. Each ODM is capable of controlling up to 7 separate outputs by applying ground to the device which the PCM is commanding ON. Unlike the Quad Driver Modules (QDMs) used in prior model years, ODMs have the capability of diagnosing each output circuit individually. DTC P1655 set indicates an improper voltage level has been detected on ODM B output 5, which controls the EVAP purge solenoid.
Conditions for Setting the DTC

* The ignition is ON.
* An improper voltage level has been detected on the EVAP purge solenoid control circuit.
* The above conditions are present for at least 30 seconds.

Action Taken When the DTC Sets

* The PCM will illuminate the malfunction indicator lamp (MIL) during the second consecutive trip in which the diagnostic test has been run and failed.
* The PCM will store conditions which were present when the DTC set as Freeze Frame and Failure Records data.

Conditions for Clearing the MIL/DTC

* The PCM will turn OFF the MIL during the third consecutive trip in which the diagnostic has been run and passed.
* The History DTC will clear after 40 consecutive warm-up cycles have occurred without a malfunction.
* The DTC can be cleared by using the scan tool.

Diagnostic Aids

Check for the following conditions:

* Poor connection at the PCM or the EVAP purge valve. Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.
* Damaged harness. Inspect the wiring harness for damage.
* If the harness appears to be OK, disconnect the PCM, turn the ignition ON and observe a voltmeter connected between the EVAP purge valve control circuit and ground at the PCM harness connector while moving connectors and wiring harnesses related to the EVAP purge valve. A change in voltage will indicate the location of the malfunction.

Reviewing the Fail Records vehicle mileage since the diagnostic test last failed may help determine how often the condition that caused the DTC to be set occurs. This may assist in diagnosing the condition.
Test Description

Number(*) below refer to the step number(*) on the Diagnostic Table.

2.

Normally, ignition feed voltage should be present on the control circuit with the PCM disconnected and the ignition turned ON.
3.

Checks for a shorted component or a short to B+ on the control circuit. Either condition would result in a measured current of over 500 milliamps. Also checks for a component that is going open while being operated, resulting in a measured current of 0 milliamps.
4.

Checks for a short to voltage on the control circuit.
15.

This vehicle is equipped with a PCM which utilizes an Electrically Erasable Programmable Read Only Memory (EEPROM). When the PCM is being replaced, the new PCM must be programmed.

P0740
Circuit Description

In conjunction with the Torque Converter Clutch Pulse Width Modulation Solenoid Valve (TCC PWM Sol. Valve), the Torque Converter Clutch Solenoid Valve (TCC Sol. Valve) controls the fluid acting on the TCC converter clutch valve. This controls the TCC apply and release. The PCM monitors the throttle position, the vehicle speed and other inputs in order to determine when to energize the TCC Sol. Valve. Circuit 639 supplies ignition voltage directly to the TCC Sol. Valve. The PCM controls the TCC Sol. Valve by providing the ground path through circuit 422. When you command the TCC Sol. Valve OFF, the PCM receives high voltage. When you command the TCC Sol. Valve ON, the PCM receives low voltage.

If the PCM detects low voltage when the TCC Sol. Valve is commanded OFF or high voltage when the TCC Sol. Valve is commanded ON, then DTC P0740 sets. DTC P0740 is a type A DTC.
Conditions for Setting the DTC

* The system voltage is 10-16 volts.
* The engine speed is greater than 500 RPM for 5 seconds.
* Not in fuel shut off
* The PCM commands the solenoid ON and the voltage remains high (B+).
* The PCM commands the solenoid OFF and the voltage remains low (0 volts).
* All conditions must be met for 5 seconds.

Action Taken When the DTC Sets

* The PCM inhibits TCC operation.
* The PCM inhibits 4th gear, if the transmission is in hot mode.
* The PCM illuminates the Malfunction Indicator Lamp (MIL).

Conditions for Clearing the MIL/DTC

* The PCM turns OFF the MIL after three consecutive ignition cycles without a failure reported.
* A scan tool can clear the DTC from the PCM history. The PCM clears the DTC from the PCM history if the vehicle completes 40 warm-up cycles without a failure reported.
* The PCM cancels the DTC default actions when the fault no longer exists and the ignition is OFF long enough in order to power down the PCM.

Diagnostic Aids

* Inspect the wiring for poor electrical connections at the PCM. Inspect the wiring at the transmission 7-way connector. Look for the following problems:
o A bent terminal
o A backed out terminal
o A damaged terminal
o Poor terminal tension
o A chafed wire
o A broken wire inside the insulation
* When diagnosing for an intermittent short or open, massage the wiring harness while watching the test equipment for a change.

Test Description

The numbers below refer to the step numbers on the diagnostic table.

6.

This Step isolates the fault between the engine harness and the transmission harness.
8.

This Step verifies that circuit 422 is not open or shorted to power.
12.

This Step verifies that the TCC Sol. Valve is not shorted across its windings or increased its resistance.
