Question about 1996 Mercury Sable

1 Answer

Cam Shaft Sensor???

Okay lets just start off with I'm FEMALE!!! I know a little about what's under the hood of a car and most of my knowledge has come from fixing the problems that occur. But now I'm a fish outta water. My Sable will be driving along hum dee hum, and then just shuts off. No sputter, no warning. I can put it in neutral and crank it right back up now that I have replaced the battery and terminal connectors. When stopped it will idle irregularly and actually kinda high. Also makes a whining noise....I've checked the fuel pump, replaced the fuel filter, had the injectors burned, serpentine belt is new, checked all fluids and all were fine. So I took myself down to the shop and had them run a diagnostics test. The mechanic told me that the only thing it's showing that could be causing my problems is a bad cam shaft position sensor. And wants to charge me an arm and a leg for it. And then he said that is where he thinks we should START! If that IS the problem that's one thing but I don't wanna blow alot of cash on trial and error. So I was hoping to replace the sensor myself but I can't seem to it!!! Can some one PLEASE steer me in the right direction! And if anyone else has had this problem please let me know what it took to fix it! I'm willing to spend the money on the sensor if that is what it is but like I said I'm not up for russian rullet.

A. The Camshaft Position Sensor is located at the left side of the engine block, between the cylinder heads.
CAUTION: Syncro Positioning Tool T95T-12200-A (303-529) must be obtained prior to installation of the replacement synchronizer assembly. Failure to follow this procedure will result in the fuel system being out of time with the engine, possibly causing engine damage.
REMOVAL:
CAUTION: Prior to removal of the Camshaft Position (CMP) sensor, set cylinder No.1 to zero degrees Top Dead Center (TDC) of compression stroke. Note the position of the CMP sensor electrical connector. The installation procedure requires that the connector be located in the same position.

  1. Disconnect battery ground cable. NOTE: When the battery has been disconnected or connected, some abnormal drive symptoms may occur while the Powertrain Control Module (PCM) relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.
  2. Disconnect engine control sensor wiring connector from CMP sensor.
  3. Remove CMP sensor retaining screws and CMP sensor from sensor housing.
  4. If removing CMP sensor housing from the cylinder block, proceed with Removal Step 5. If not removing sensor housing, proceed to installation Step 6.
  5. Remove hold-down clamp (bolt and washer assembly).
  6. Remove CMP sensor housing from cylinder block.
INSTALLATION:
CAUTION: A special service tool such as Syncro Positioning Tool T95T-12200-A must be used to position the synchronizer assembly prior to installation of the CMP sensor. Failure to follow this procedure will result in improper sensor alignment. This will result in the fuel system being out of time with the engine, possibly causing engine damage.
  1. Attach Syncro Positioning Tool T95T-12200-A as follows:
    1. Engage camshaft position sensor housing vane into the radial slot of the tool.
    2. Rotate tool on CMP sensor housing until tool boss engages notch in sensor housing.

  2. Pre-lubricate synchronizer gear with engine oil meeting Ford specification ESE-M2C123-A prior to assembly.
  3. Install CMP sensor housing so that drive gear engagement occurs. Locate CMP sensor electrical connector in the pre-removal position.
  4. Install hold-down clamp (washer and bolt) and tighten bolt to 19-30 Nm (14-22 lb ft).
  5. Remove Syncro Positioning Tool T95T-12200-A.
  6. Install CMP sensor and retaining screws. Tighten screws to 1.5-4.0 Nm (14-35 lb in).
CAUTION: If CMP sensor electrical connector is not positioned properly, DO NOT reposition the connector by rotating the sensor housing. This will result in the fuel system being out of time with the engine, possibly causing engine damage. Remove the sensor housing and repeat installation procedure, beginning with Step 1.
  1. Connect engine control sensor wiring connector to CMP sensor.
  2. Connect battery ground cable.

2000 dodge neon will not start unless the cam shaft sensor is unplugged


I would go and but a cam sensor from the dealer. Aftermarket cam sensors can be slightly irregular. I had this happen to me with an aftermarket ABS sensor on a chevy. The whole problem was a gap difference equal to two sheets of paper. Whats happening is there is an open circuit in your old sensor that causes the check engine light but the new one has a good circuit but bad reading. I would say that is your problem.

I have a jeep that will not start it gets no spark it will turn over


From what I read crank shaft sensor and cam shaft sensor. Are your dash gages working right? If not the fuse panel under the hood is corroded and needs longer screws 3/4 instead of 1/2 inch where battery connects

I need to know where the Cam Shaft sensor is for my 2005 PT Cruiser is. My car is sputtering and the car is not starting when the switch is turn on.


the cam sensor is near the battery. it is on the end of the cylinder head rear. you should have a code po340 if the cam sensor is bad. get someone to scan it before replacing the sensor . check under the car for a wire rubbing on the cv shaft that goes to the crank sensor.

Sometimes it will start sometimes it will not. I will go out and try and start it and it will not start, i'll go our a couple hrs later and it will start. I have replaced cam shaft sensor,crank shaft...


This sounds like a problem with the fuel pump relay. Go into your under-hood fuse box and find the relay that operates the fuel pump. Switch it with another relay that is similar, and see if you still have the same trouble with the vehicle.

After a while, the electrical contacts inside of the relay tend to foul up from use. This same thing recently happened on my friends' 2003 Saturn Vue.
