Passat 2001 with codes P0012,P0340 it runs fine the turbo kicks in no problem I originally found some broken vaccum line and replaced them but the codes still return


P0340 - Camshaft Position Sensor Trouble
Your cam timing timing is off and the sensor is fine. They are very simple sensors...it's just a magnet...and magnets don't go bad. Check the timing. Incorrect allocation means that the camshaft isnt where the computor thinks it should be at any given time. This could be casued by the base engine timing being off by a tooth or by a problem in the camshaft adjuster.


P0012 Camshaft A: Advance Setpoint not Reached
The code P0012 can be set by the following concerns: Faulty cam adjuster, Faulty cam adjuster solenoid, Low oil pressure, Sludged oil passages and Sticky camshaft.

The variable cam timing uses engine oil pressure diverted to the adjuster mechanism by a solenoid duty cycled by the PCM. Low oil pressure or severe oil sludging can affect camshaft timing operation. Always check oil level and condition when camshaft adjustment codes are present.

Using a full function Volkswagen compatible scan tool enter address word 01 (Engine). Function 08 (Read Measuring Value Blocks) and Display Group 091 (Power Enhancement Camshaft Adjustment).

Observe the 4th display field "Active Camshaft Adjustment Angle" With the engine at idle. The 4th display field should read between -3.0 to +6.0 degrees KW if the camshaft is in the normal unadvanced position. Any other reading at idle indicates that the camshaft is shifted from the normal unadvanced position

Accelerate the vehicle from a standstill in 1st gear using wide-open throttle and observe the display in field 4 again. Under heavy acceleration the display should read between +16.0 to +25.0 degrees KW. This indicates that the camshaft has shifted to the full advance position.

If the display in field 4 does not change from the values in test step 2 or if the display changes but does not reach a minimum of +16.0 degrees KW (i.e. between +6.0 and +16.0 degrees KW), the camshaft timing adjuster mechanism is not advancing the camshaft.

Failure to advance the camshaft could be caused by a faulty cam adjuster, a faulty cam adjuster solenoid, low oil pressure, sludged oil passages, or a sticky camshaft.


Hope this helps (remember to rating this free answer and leave ue some testimonial comment)

Try the camshaft possition sensor. I know it sounds stupid being that you changed your distributor, but most are rebuilt and they only check the continuity not function of camshaft sensor. Hope this helps!

1996 MERCURY GRAND MARQUIS WITH OCCASIONAL SLUGGISHNESS ON ACCELERATION AND SEEMS LIKE IT MAY BE USING MORE GAS THAN USUAL. HAS BEEN WELL TAKEN CARE OF, REG. OIL CHANGES, NEW FUEL FILTER 2 YRS AGO-DR


I would use 10W40 in the 96 and 5W20 or 30 in the 2002.

For the 96 with sluggishness, you need to gently clean the MAF sensor wires with carb cleaner and a toothbrush. It is in the air intake tube. After cleaning, disconnect the battery for 1/2 hour, then reconnect so the computer can relearn the clean sensor. Drive for 10 miles, it will run rough until it relearns.


Section 03-14: Engine Controls, Electronic 1996 Town Car, Crown Victoria, Grand Marquis Workshop Manual
DESCRIPTION AND OPERATION Mass Air Flow (MAF) Sensor The mass air flow sensor (MAF sensor) (12B579):
  • is mounted on the corner of the engine air cleaner (ACL) (9600).
  • uses a hot wire sensing element to measure the amount of air entering the engine; air passing over the hot wire causes it to cool.
  • sends out an analog voltage signal to the PCM (12A650) to determine the intake air mass. The PCM will then calculate the required fuel injector pulse width to provide the desired air/fuel ratio.
The mass air flow sensor hot wire sensing element and housing are calibrated as a unit and must be serviced as a complete assembly.

Black smoke and sluggish when accelerator is fully depressed


It seem like a vaccumn problem. Check the vaccumn lines especially the one going to the fuel preassure regulator. or it could be the regulator itself.
