WHERE ARE THE CAMSHAFT POSITIONING SENSOR(S) ON A 07 SEBRING 2.4?

cam and crank sensors are notorious for acting up when their temperature changes; if its got the code, it's probably bad.

I think you are referring to either a Crankshaft position sensor or a Camshaft position sensor. I've included a tutorial video below:

The timing chain on a Ford Expedition works with the camshaft and crankshaft, turning them through sprockets. The alignment with the chain and its sprockets is very precise, so replacing the chain is a very precise and difficult procedure. The chain has its own cover that you must remove to access it. Consult your mechanic before working on the timing chain. The process can vary depending on the year and engine type. Professional maintenance is always recommended.

1. Removing the Chain Cover
   • 1 Disable the truck's ignition system by disconnecting the primary electrical connectors at the ignition coil pack. Disconnect the negative battery cable before you do this.
     
   • 2 Take out the spark plugs by unplugging their wires and removing them with a socket wrench and spark plug socket.
     
   • 3 Install a compression gauge into the Number One cylinder and use a breaker bar and socket on the crankshaft's damper bolt to turn the crankshaft. Turn it until the notch in the damper aligns with the TDC mark on the front cover and compression is noted on the gauge.
     
   • 4 Drain the engine oil from the truck into a pan by removing the oil pan plug and remove the oil filter with a filter wrench.
     
   • 5 Unbolt and remove the crankshaft pulley and vibration damper; mark their positions so they can be installed the same way. Avoid turning the crankshaft as you remove the damper.
     
   • 6 Remove all accessory brackets connected to the timing chain cover by unbolting them. This includes unbolting the power steering pump; set it aside with its hoses still connected.
     
   • 7 Disconnect the camshaft position sensor's electrical connector and remove the camshaft position sensor. Disconnect the electrical connectors for the crankshaft position sensor and knock sensor.
     
   • 8 Remove the front bolts on the oil pan and the socket-head bolt--the latter requires an Allen wrench. Disconnect the heater hoses and then unbolt and pull out the heater outlet tube.
     
   • 9 Separate the timing chain cover by removing its bolts. You may need to tap it with a soft face hammer if it's stuck.
     
   Changing the Chain
   • 1 Check and see that the timing marks on the camshaft, crankshaft and balance shaft sprockets are all aligned. If not, re-install the vibration damper bolt so you can turn the crankshaft clockwise to align the marks.
     
   • 2 Remove the camshaft sprocket's mounting bolt and the camshaft position sensor's drive gear. Compress the timing chain tensioner with a screwdriver, hold the tensioner in the retracted position with a drill or Allen wrench and pull the sprocketed chain off the camshaft.
     
   • 3 Turn the camshaft until the key is facing the 12 o'clock position (straight up).
     
   • 4 Place the replacement chain on the camshaft sprocket, turn the sprocket until its timing mark faces 6 o'clock (straight down), position the chain over both sprockets with their timing marks lined up and slip the sprockets on the camshaft and crankshaft.
     
   • 5 Install the camshaft position sensor drive gear by aligning its keyway arrow with the Woodruff key on the camshaft.
     
   • 6 Install the camshaft sprocket bolt, applying a non-hardening thread-locking compound to the threads, and tighten the bolt to 30 to 36 foot-pounds.
     
   • 7 Remove the drill or wrench from the timing chain tensioner and re-install all the other parts in the reverse order of removal. This includes adding fresh engine oil and a new oil filter.
     

P1684 The battery has been disconnected within the last 50 starts.

P0340


This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.
Symptoms Symptoms can include:

• Hard starting or no start
• Rough running / misfiring
• Loss of engine power

Causes A code P0340 could mean one or more of the following has happened:

• a wire or connector in the circuit could be grounded/shorted/broken
• the camshaft position sensor may have failed
• the PCM may have failed
• there exists an open circuit
• the crankshaft position sensor may have failed

Possible Solutions With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

• Visually inspect all the wiring and connectors in the circuit
• Check for continuity in the circuit wiring
• Check the operation (voltage) of the camshaft position sensor
• Replace the camshaft position sensor as required
• Check the crankshaft position circuit as well
• Replace circuit wiring and/or connectors as required
• Diagnose/replace the PCM as required

Test it and keep us updated.

There is a bulletin (or recall depending on your mileage) for this issue. The timing chain stretches due to lack of oil lubrication. The acadia engine is very sensitive to timing chain stretch. There are 2 things they will do. The first is a reprogram to let the PCM adjust for minimal extra slack, they will say to drive it and if it doesn't come back on you're good just keep up with the oil changes (5k miles or less with dexos oil). If that doesn't work they will have to drop your engine and replace all 3 timing chains. It's an all day event and may even take an extra day.

camshaft position sensor is at the back end of the camshaft. should be just across from the battery.

check code probable p0340 camshaft position sensor. I have the same problem on 2005 sebring sedan. I was told to check the circuit at the crankshaft and camshaft sensors for the proper voltage. I'm still trying to figure mine out. If you find your answer, let me know.

TRY A TUNE UP OR THE COIL PACK I HAD THE SAME PROBLEM
