code is P0449

The PCM has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system.

EVAP (Evaporative Emission System) purge/vent solenoid circuit condition

The solenoids and system wiring are monitored for opens or shorts

Probable Causes
1- Purge or vent solenoids defective
2- Check connevtor and wiring
3- Fuel saturated vapor canister
4- Failed EVAP vent solenoid

A code P0141 may mean that one or more of the following has happened:

  • open or short to ground in the wiring harness
  • O2 heater circuit wiring high resistance
  • O2 heater element resistance is high
  • Internal short or open in the heater element
Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.
Possible Solutions
  • Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
  • Repair short or open or high resistance in wiring harness or harness connectors

I have a passkey 3 on my 2002 cadillac deville and the security system is not letting my car start or crank does anyone know how to fix this problem i'm having without me having to take it to a dealer

You need a capable scan tool to check DTC'S - diagnostic trouble code's .
DTC B2734
DTC B2960
DTC B3031
DTC B3055
DTC P1630
DTC P1631

These would tell why the PCM - engine computer isn't starting the vehicle . There is no by-pass for this anti-theft system . The Dealer is your only hope . Nothing you can do !
The theft deterrent control module produces the theft deterrent fuel and starter enable signal when ignition is ON and the proper transponder key value is detected. The powertrain control module (PCM) monitors the fuel and starter enable signal during crank. If the proper signal is present on the Class 2 Serial Data Circuit, the PCM enables the fuel delivery and starter operation in order to allow the engine to start. If the PCM detects an incorrect password, vehicle theft deterrent (VTD) system failure or attempted vehicle theft, DTC P1631 is set. The engine will not start or crank as long as the condition is present.

I've got a 2001 Cadillac deville and it says it's lost the IRC ID and IRC data code. any idea how that happen?

When a malfunction such as an open fuse to a module occurs while modules are communicating, a DTC U1001-1254 Loss of 000 Communications is set current. When the modules stop communicating the current DTC U1001-1254 Loss of 000 Communications is cleared but the history DTC remains. When the modules begin to communicate again, the module with the open fuse will not be learned by the other modules so U1000 or U1255 is set current by the other modules. If the malfunction occurs when the modules are not communicating, only U1000 or U1255 is set. Radio quit working shows Code IRC U1000 please help

Where is the VTD relay located at on my 2001 cadilliac deville, and what is the easiest way to get to it? also where do I start trouble shooting VTD?

There isn't any VTD relay on your vehicle ! You start trouble shooting by checking for DTC's diagnostic trouble codes .
The vehicle theft deterrent (VTD) system functions are provided by the theft deterrent control module. The VTD system prevents vehicle operation if a valid (learned) transponder PASS-Key®III (PK3) ignition key is not used to start the vehicle. The PK3 key has a transponder embedded in the plastic head of the key. The exciter is an antenna which is made up of wire coils which surround the ignition lock cylinder. The powertrain control module (PCM) enables engine starting when it receives a valid (learned) password from the theft deterrent control module via the class 2 serial data circuit. The components of the VTD system are as follows:
• The theft deterrent control module
• The powertrain control module (PCM)
• The ignition key (Transponder)
• The ignition lock cylinder
• The security indicator
Your best bet would be to have your vehicle taken to a qualified repair shop .

P1626 1997 chev silverado 1500 are they fix for this problem

DTC P1626 Theft Deterrent Fuel Enable Signal Not Received
The control module communicates with other modules using the Class 2 Serial Data circuit. The vehicle theft deterrent (VTD) (Passlock) module sends a vehicle security password to the control module, via the Class 2 Serial Data circuit, after the system has sensed the proper operation of the ignition switch and lock, and determined that the switch and lock have not been tampered with. If this password matches the password stored in the control module, fuel will be enabled. If the VTD (Passlock) module does not send a password, or if the control module does not receive it, the vehicle will not start, or it may start and stall. This will set a DTC P1626 in the control module memory. If communication is lost after receiving the password, the VTD (Passlock) system will go into Fail Enable, set a U1192 in the control module, and the engine will continue to run. This will allow the engine to restart on future ignition cycles but may set a DTC P1626 as the engine is started. If the battery is disconnected or the codes are cleared, the vehicle will lose its Fail Enable status and will not start until communication is re-established
Go on YouTube an search passlock by pass , or you can take it to the dealer .

I get codes or DTC's that i have no idea what would cause them? IPC 04610, IPC P1610, IPC U1255, AMC B1348, SDM U1255, IRC U1255

OBDII Code U1255 CADILLAC Lost Communications HelpForCars net P1610 Cadillac how to repair
DTC B1348 Very Low A/C Refrigerant Pressure
DTC U1255 Serial Data Line Malfunction
The class 2 serial data line communicates information between the modules. Each module connected to the serial data line is assigned a recognition code, or address. This code is used in order to identify which modules are communicating. Modules communicate with each other by periodically sending state of health (SOH) messages. When the ignition switch is in RUN, each module that is communicating on the serial data line sends an SOH message every 2 seconds. This ensures that the system is operating properly. At key on, most modules must learns the initiation data from other modules on the serial data line. When a module requests initialization data from another module, and that request is not acknowledged after 5 seconds, the module stores class 2 initialization error DTC U1255.
Conditions for Setting the DTC
The module does not receive required initialization data on the class 2 serial data line. The module retries the request for 5 seconds, and then sets DTC U1255.

This DTC only sets if DTC U1300 or U1301 are not current

Attempt to establish communication with all of the modules using a scan tool.
Does the scan tool communicate with all of the modules?
Go to Step 3
Go to the appropriate diagnostic system check for the module that is not communicating

My dad owns a 2003 CTS. While driving the car he gets the displayed message "starting disabled remove key" and the car shuts off. He puts the car in NEUTRAL and WITHOUT removing the key, starts the car...

Refer to Theft Systems Description and Operation in Theft Deterrent

The radio illuminates the STARTING DISABLED REMOVE KEY message when the VTD system has disabled the starting system. The radio receives a message from the theft deterrent control module via the serial data circuit requesting illumination.

Your best bet ,take it to Cadillac dealer and have it checked . Could have DTC'S - diagnostic trouble codes
DTC B1015
DTC B1016
DTC B3031
DTC B3055
DTC B3060

The theft deterrent module or the insturment cluster or the ECM is not seeing correct info.
The vehicle theft deterrent (VTD) system functions are provided by the theft deterrent control module. When an ignition key is inserted into the ignition lock cylinder and the ignition is switched ON, the transponder embedded in the head of the key is energized by the exciter coils surrounding the ignition lock cylinder. The energized transponder transmits a signal that contains its unique value, which is received by the theft deterrent control module. The theft deterrent control module then compares this value to a value stored in memory, learned key code. If the value is correct the theft deterrent control module sends a random generated number to the transponder, this is called a challenge. Both the transponder and the theft deterrent control module perform a calculation on the challenge, if the calculations match the theft deterrent control module sends the fuel continue password via the serial data circuit to the Engine control module (ECM). If either the transponders unique value or the calculation to the challenge is incorrect the theft deterrent control module will send the fuel disable password to the ECM via the serial data circuit. The components of the VTD system are as follows:
• Theft deterrent control module
• Engine control module (ECM)
• Ignition key (Transponder)
• Ignition lock cylinder
• Security indicator

I have a 93 caddy deville and cannot find a site to tell me what the codes mean

this site has alot of info:

Hope this is what you need!!!

ABS (Antilock Brake System)
AMP (Amplifier)
DDM (Door Driver Module)
DIM (Dash Integration Module)
IPC (Instrument Panel Cluster)
IPM (Instrument Panel Module)
IRC (Integrated Radio Module)
PCM (Powertrain Control Module)
RFA (Remote Function Actuation)
RIM (Rear Integration Module)
SDM (Sensing and Diagnostic Module) Includes airbag crash data. Under RF seat
VTD (Vehicle Theft Deterrent)
MSM (Memory Seat Module)
TTM (Tilt/Telescoping Module)
RSS (Road Sensing Suspension)

How To Pull Codes To check for Diagnostic Trouble Codes stored in the computer, turn the ignition on, then hold down the OFF and WARMER (for digital dash) or OFF and passenger-WARMER buttons (for analog dash) or OFF and "Info ^" buttons (if you have temperature dials) until all of the dash lights come on. The digital display will then show any codes stored. Be prepared to write them down. When it's done, you will probably see "PCM?" At that point, press the OFF button 3 or 4 times until the dash goes back to normal, or just turn off the ignition.
