Retrieved codes P0191, P0152, P1246, P1233 and P1000 on my 02' Taurus 3.0 OHV. What would be the most likely culprit causing these codes?


P1000 - Monitor Testing Not Complete The on board diagnostic II (OBD II) monitors are performed during the OBD II Drive Cycle. The DTC will be stored in continuous memory if any of the OBD II monitors do not complete.
  • Vehicle is new from the factory
  • Battery or PCM had recently been disconnected
  • An OBD II monitor failure had occurred before completion of an OBD II drive cycle
  • PCM DTCs have recently been cleared with a scan tool
  • PTO circuit is shorted to VPWR or B+ or PTO is on during testing
The DTC does not need to be cleared from the PCM except to pass an inspection/maintenance test

I have a vw passat TDI130 2003. It runs really well, but engine workshop lights up along with the esp, abs and the glow plug indicators lighting up, most garages are charging just for a diagnosis to the...


Check & replace if necessary the brake pedal switch placed above pedals on the support.
If the problem still occurs you might access the ESP & ABS ECU (Electronic Control Unit) using diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC (Diagnostic Trouble Codes) memored.
Then you will be able to replace bad piece(s) and fix the problem by erasing all DTC stocked inside ESP & ABS ECU & reset it.
I'm convinced that your brake pedal switch is faulty because the glow plug warning light went ON, along with the ESP & ABS. Just replace the brake pedal switch, see if rear stop lamps light when press the brake pedal, and test the car on the road.

Where is the diagnostic port located on my 2001 passat 5 sp. auto V6?


On the old Volkswagen Passat B5 (MY 1997-2001) the Data Link Connector (DLC) or diagnostic port is placed on the right side of the parking brake lever, under a small rectangle rubber cover. See pictures below:

What are the cause of a mil light on 2002 vw jetta- how cna one diagnosi this under the hood? can cold weather be a cause and can this correct itslef


Check the MIL code to see what exactly is the problem. For instance, it may be an O2 sensor that has been damaged in the cold.
Please read the following link. It is a great source to troubleshoot MIL codes.

Volkswagen Diagnostic Trouble Codes
DTC Table - General

From model year 1996, vehicles manufactured for the North American market are equipped with a Government required diagnostic system known as On-Board Diagnostics II (OBD II). This system monitors operation and function of all engine management system activity and automatic transmission operation to insure compliance with specified emission levels.

Vehicle emission levels are constantly monitored by the OBD II system and malfunctions are recognized and recorded. A Malfunction Indicator Light (MIL) in the instrument cluster alerts the driver to the fault and the need to have the system checked for fault codes. These codes follow a standard format and are known as Diagnostic Trouble Codes (DTCs).

DTCs are assigned two codes. The first code is a numerical code assigned by the factory. The second code is referred to as a P-code and follows a structure required by law and defined by the Society of Automotive Engineers (SAE). This standard uses a letter to designate the system and four numbers to further identify and detail the malfunction as listed below.

I need to remove the words 'service now' from my volkswagen passat


It is not possible to have that reset or turned off "Service now!" without using a diagnostic scantool connected to the data link connector of the car. This is the only one way to reset service due light on a 2008 Volkswagen Passat.

Looking for the OBDll connector for a 1996 Toyota Corolla ll Windy Model with a1N-T, 1453 cc turbo diesel engine. Steering wheel is on the passenger side of the car. Need this info for a friend. He has...


Look under the dash near where the steering wheel is usually located (on the driver's side).

Was this vehicle marketed in the U.S.?
1996-97 MODELS NOTE: These models require the use of the Toyota's hand held scan tool or an equivalent OBD II compliant scan tool.
  1. Prepare the scan tool according to the manufacturers instructions.
  2. Connect the OBD II scan tool, to the DLC3 under the instrument panel. The DLC3 on the 1996-97 models is located on the drivers side under the dash 88274pa2.jpg
    NOTE: When the diagnosis system is switched from the normal mode to the check mode, it erases all Diagnostic Trouble Codes (DTC) and freeze frame data recorded. Before switching modes, always check the DTC and freeze frame data and write them down.
  3. Turn the ignition switch to the ON and switch the OBD II scan tool switch on.
  4. Use the OBD II scan tool to check the DTC and freeze frame data. Write them down.
  5. Compare the codes found to the applicable diagnostic code chart. If necessary, refer to the individual component tests in this section. If the component tests are OK, test the wire harness and connectors for shorts, opens and poor connections.

I am getting a p0171 code on my 2005 volkswagon passat what does that mean


P0171 - Fuel Trim, Bank1 System too Lean
VW DTC 16555 (P0171) - Fuel Trim, Bank1 System too Lean
By only pulling battery power from the ECU doesn't clear the codes on OBDII systems.
You must have access to a VAS, VAG-COM, Bosch KTS, ... diagnostic scantool. The ECU (Electronic Control Unit for engine management) is seeing a fuel trim that's much too lean even with the ECU making adjustments. Colud be the MAF (Mass Air Flow) sender out of order, the pre-cat O2 sensor, or a significant vacuum leak. You need to confirm / deny working parts with a 2nd gear pull data-logging measuring blocks 002, + 032 (VAS, VAG-COM).
