Camshaft Position Sensor
The camshaft position (CMP) sensor detects the position of the camshaft. The CMP sensor identifies when piston No. 1 is on its compression stroke. A signal is then sent to the powertrain control module (PCM) and used for synchronizing the firing of sequential fuel injectors. The Coil On Plug (COP) Ignition applications also use the CMP signal to select the proper ignition coil to fire. The input circuit to the PCM is referred to as the CMP input or circuit.
There are two types of CMP sensors: the three pin connector Hall-effect type sensor (Figure 25) and the two pin connector variable reluctance sensor

Summary


Should a customer express concern about one of the following:


* hesitations,
* poor or no start,
* deteriorated fuel economy,
and upon investigation diagnostic trouble codes (DTC) P1412, P0490 and P1335 are stored in the powertrain control module (PCM), the probable cause is a sticky exhaust gas recirculation (EGR) valve.


To rectify this concern, a new EGR valve with a stronger EGR valve motor and revised PCM calibration should be installed.

Check the wire connections grounded to the chassis.

if you haven't bought the belt yet, go to auto parts store (autozone), they'll probably offer you the correct size & the diagram.

I found my button needed cleaned and I made a video on how I did that. I also found some wires to the latch had insulation cracked and I show where I found that in the video.

2003 Ford Focus | Answered on Sep 11, 2015


Here's a video I made on what all I found wrong with mine. First you want to make sure the fuse is not blown. I had to clean my trunk latch button and I show how to do that in the video. I also found the wires going to the trunk latch had split insulation and I show where I found that problem in the video.

2003 Ford Focus | Answered on Sep 11, 2015


I agree with the first answer because that's what fixed mine and I made a video on how to do it. I also found the wire bundle going to the trunk had all the wire insulation cracked open and one wire broke. Watch the video and I'll show it all.

check brake light switch for clearance,or interferance

2003 Ford Focus | Answered on Aug 13, 2015


I agree that it's probably seizing up and here's a video I made on how to change the compressor. You also need to change the accumulator and orifice tube when you change the compressor. If the compressor came apart and threw chunks or metal shavings into the system, it's recommended to flush the system but that didn't happen on mine, so I don't show how to do that.

I assume it's because your clutch is engaging and disengaging. Could be from a loose electrical plug to your compressor coil on the compressor. It could be a loose plug to the pressure sensor or a bad pressure sensor because that sensor will shut it off if the car is low on Freon causing low pressure in the system. Could be low on Freon so it's on the edge of having enough pressure to turn it on and then shuts it down again because it dips below the pressure threshold when the compressor kicks in. Could be a bad compressor coil that engages the clutch. Maybe a loose connector to the AC Button in the car or the AC Button is intermittent. Could be an intermittent relay engaging the compressor clutch. That's a good list of what all could cause it and if you end up needing to replace the compressor, I made a video on how I did it.
