My 2003 Ford Taurus is giving me a code of P0340 - CAM Position Sensor Circuit Fault. Secondary code of P1336 - Misfire Monitor Hardware. Anyone had a similar fault code and will changing the CAM Sensor correct? Or is this going to become one problem fix to find another?
I would think it would be just the Camshaft Position Sensor.I looked up the codes and they say pretty much the samething.

Recently I have had problems with a 2003 Ford Taurus stalling while idling at a stop sign or light. I. The engine light came on., so I took the car to Auto Zone to have the OBD engine code read. The codes were P0171 (System Too Lean (Bank 1)) and P0174 (System Too Lean (Bank 2)). The AutoZone rep. said that the 2 oxygen sensors (1 for intake, and 1 for exhaust) need replacing. Also he said that the Mass Air Flow and Idle Air Control Valve sensors needs replacing.
What I have seen is a noticeable increasing vacuum leak as the engine warms up coming from the front part of the engine directly under the intake manifold. I have followed the (aprox 1/2'' dia..) vacuum line that starts just after the MAF sensor to what appears to be a sensor or connector? I can not tell what the sensor/connector is without taking the manifold and various related components off. Anyway, when I completely disconnect this vacuum line the car dies out immediately. This sensor/connection has nothing to do with the O2 and MAF sensor. I have tried to find a vacuum routing and component diagram for the 3.0L, V6, Duratec but engine compartment has none. Can some one tell me where a vacuum diagram might be available, or what this leaking component is called so this problem can be solved?
go to autozone.com and register for free. You will then have a full free online repair manual with step-by-step directions, diagrams, troubleshooting, testing, replacing, and more. As an automechanic myself, this a wonderful site.

changing oil pan gasket 2003 ford taurus is it easy
Hi,
Disconnect the battery. You will need to put the car up on jack stands,
get under the car, drain the oil, remove the catalytic converter (which
can be aggravating without a lift hoist, which I am assuming you don't
have), remove the starter and flywheel cover, remove the oil pan (held
on by about twenty 8mm bolts all the way around), clean the gasket
surface, install a new gasket (put a small amount of RTV in the corners
only!), install the pan (tighten the bolts evenly to about 100 inch
pounds--CAUTION: that is not very tight, do not over tighten!), reinstall
everything, fill the oil, and happy trails.
"Which can be
aggravating" only hints at the misery you will invite when you have to
remove the Y pipe assembly attached to the catalytic converter. Before
you remove the first screw on the oil pan, make sure you can do it. I
spent most of yesterday prepping the surfaces, working the gasket in
from the outside of the pan and getting the silicone and screws done
with 1 1/2 " of clearance, because I couldn't. No leaks, but oh my god.
As my dad would have said "It could make a preacher cuss."
Good luck.

car has stalled out twice within last 30 days
The code is for the fuel rail pressure sensor / circuit.
Problems could include a failed sensor, high or low fuel pressure, or wiring problems between the sensor and the computer.
Low fuel pressure can be caused by a dirty filter or a failing pump.

tools for diagnosing that

Where is the anti theft box located on 2003 ford Taurus?
The PATS - passive anti-theft system is a program (software ) programmed into the instrument cluster , PCM - engine computer , GEM module etc... Plus behind the plastic shroud on steering column where the lock cylinder is located the passive anti-theft transceiver module ! You better know what your getting into when you start to mess with anti-theft systems , you can render your vehicle useless if your not careful ! Need factory scanner to program keys , to read trouble codes , check data etc... If you change transceiver module it will need to be programmed ! FORD DEALER ONLY ! You can program more keys but need to have original two keys that came with the vehicle or you can't do it >
Passive Anti-Theft System (PATS) -Principles of Operation
PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code out of over 18 billion, billion combinations.
The passive anti-theft system (PATS), also known as SecuriLock ®, uses radio frequency identification technology to deter a drive-away theft. This system is known as SecuriLock® in North America, Safeguard® in the U.K., and PATS in Continental Europe. Passive means that it does not require any activity from the user.
The SecuriLock® System (PATS) is not compatible with non-Ford aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. If equipped, the remote start system must be removed before investigation of PATS-related, no-start issues.
Each encoded ignition key must be programmed into the vehicle powertrain control module (PCM) before it can be used to start the engine. There are special diagnostic repair procedures described in this section that must be carried out if a new encoded ignition key is necessary.
The correct ignition key is a different design than prior model years. Please consult the Rotunda Key Ordering Guide for the correct part number.
So , before messing with something you know nothing about , do yourself a favor , take it to the nearest FORD dealer !
So
