Camshaft Sensor Magnet may Damage Synchronizers on Mercury Sable

Problem Description and Possible Solution

The magnet for the camshaft position sensor may fall out of its mount and damage the synchronizers. This causes long crank times when starting the engine and may cause the Check Engine Light to illuminate. If this happens, both the magnets and the synchronizers need to be replaced.

The magnet on top inside of the CPS Camshaft Position Sensor broke off causing damage to the "tooth" part of the Camshaft Synchronizer and actually braking the cap or CPS in half. The check engine light did come on and report error code P0340. Both the CPS and Synchronizer needed replacement. While it can be a chore to get to this buried part (figuring it out can be harder than actual work) the actual replacement is a breeze, but you have to be careful about replacement. Apparently you only need the special tool if you don't pay specific attention to 1)placement of the "tooth" within the synchronizer and 2) placement of the synchronizer casing into the block. Taking pictures and marking the parts for exact placement is highly recommended. Other than this it is just one bolt. You can find taurus user forums with detailed instructions. Oh, I've heard the Dorman part has been known to fail VERY quickly - people have highly recommended either Motorcraft or A1 Cardone. This also fixes a chirping sound that occurs when the synchronizer fails on its own at which time it is very important to change as this can affect oil circulation.
camshaft synchronizer causing cam sensor to provide ECM with erractic readings r&r synchronizer assembly with new cam sensor
Car start up great, when driving the car, It shift slowly to 2'nd gear, as I ease off the gas it O K, then it ride O K.
The "Check Engine Soon" light on the dash illuminated, and I took it to my local mechanic (ASE Certified) who told me about the sensor. He stated it could only be repaired by a dealer because a special tool was required & was available only to dealers. The dealer wanted to charge me almost $800.00 for this repair - the exact same repair I had done about 7 years ago for $229.00, parts and labor!
Check engine light came on code p0340 came up. Camshaft position sensors signal has error not had fixed
Haven't fixed it yet but my mechanic says it's the cam shaft positioner or the sensor but getting to it requires a specialized tool because of where it is in the engine. He's a small shop so doesn't own the tool, says I need to go to a Ford shop. Estimates about $600 for the repair.
My check engine light came on two days before this happened. I was gonna take it in on pay day which was in 3 days and get it looked at. I was turning on to my friends street to drop him off at his house. Not hot rodding, not driving fast, but doing the speed limit. When I slowed down to make the turn, it dies. When I turn the key to restart it... it takes a full 6 second s to crank. When it does there's a terrible knock like someone hitting metal with metal, and a god awful squeak. We make it to his driveway just down the street, and it dies again, we roll into his yard. We get out, pop the hood, and turn it over again. The engine shakes as if the cams are warped or like the pistons are hitting the heads. And it dies. We do not crank it again. The engine almost seized right then and there. What's wrong? The engine was just rebuilt 3 months before this, and the car only has 92,000 miles on it.
If shutting off the motor with the car in drive will mess with the pcm,or the transmission reange sensor how do you reprogram the tr sensor and fix the problem
the car was missing, I had the pack that holds the spark plugs replaced, it still misses so they told me to take it to the dealer, it sounds like it might be the computer system. what price range would i be looking at?
