4.6 the twocrankshaft position sensors are located on the front of the block just above and to the left of the oil filter. not hard to replace.

This is a common problem of Volvo S40. You can try this trick to turn off the flashing arrow light.
1) Turn off Engine
2) Turn key to "On" position (Not start the engine), you will see the panel light will on
3) Step on the break paddle
4) Shift the gear from "P" to "L" 10 times
5) Turn key to " Off" position
6) Now you can start the engine.
7) If doesn't work, you can repeat the procedure.
Hope this tick help

It's located near the cam gear on the front of the engine however, the crank sensor, to the right of the oil filter near the bell housing is the part notorious for going out on these cars, and causing a p0322 and/or p0341 code, and sometimes others as well To replace the crank sensor you have to: Support the motor with a floor jack. Remove the starter, 2 of the starter bolts connect to the motor mount. Remove the motor mount from the frame, very easy. Remove the oil filter. That will give you just enough room to get an allen wrench in to remove the bolt holding the sensor in.

Lincoln LS's are good for the ignition coils going bad. This mimics a transmission issue trying to accelerate going uphill. Take your car to a LINCOLN dealer and have them do a stress test on the coil pack. It will tell them which one is bad. Also if your car is a 3.9 V8 and was built in the Wixom plant (you can tell by the VIN) google it. All of your coil packs and gaskets are covered for 10 yrs or 100,000 miles whichever comes first. It is listed in the TSB's

look in the manual......turn the ignition to the on position not starting it of course and then pump the gas petal 5 times then the light will blink a few times turn off then back on...problem solved

Where is it located? the
crank sensor is located on the 'back' of the engine on the edge of the flywheel
housing above the starter motor mounting.
A common symptom is Hesitant acceleration,
acceleration ceiling - Miss-timed ignition due to a faulty CKP signal can be exacerbated by
increased engine speed. The engine maybe run evenly at idle but will fail to
accelerate properly at higher revs until the engine reaches a power ceiling
How to check? Often the voltage output from faulty CKP sensors declines with temperature rise so a car that seems to be fine initially can become erratic after 20 minutes. If the CKP has died completely there will be very high resistance between the device's electrical connections = open circuit. Furthermore spark delivery to the plugs will be absent. First check that the electrical connection is clean and secure; dirt or corrosion can impair an otherwise healthy CKP signal from getting through. If the CKP suffers from a drop in voltage associated with heat increase this can only be detectable with a voltmeter or oscilloscope with a graphical display; an analogue display voltmeter might just be able to show needle fluctuations due to voltage variation output.
2 pin socket (magnetic - sine wave
output). One pin is 'ground' the other
is 'signal'. A voltmeter set to 2 volts
AC should measure a signal in the 0.2 to 2 volts range on the 'signal' pin.
pin socket (Hall effect, magneto - square wave form output). One pin is 'reference' (5volts), one pin is
'ground' and the third pin is 'signal'.
A DC voltage should be detectable in the 0.5 to 1.5 volt range from the
It is important that the voltage
measurement take place at start up when the engine is cold and again, 20
minutes later, when the engine has fully warmed up to operating temperature.
How to fix? Check the wiring for continuity and
that the electrical connection is clean and secure. Remove the CKP and clean off any dirt build up
on the tip.
If you strongly suspect the crank sensor as being at fault it is a relatively inexpensive device to replace.
