SOURCE: where is located the map sensor on a f-150 2004

MAP sensor is usually a square looking thing with a vacuum line and electrical connector attached to it. If you somehow meant the MAF sensor then it is located in the air intake hose near the throttle body. Hope this helps.

MAP sensor is usually mounted to the fire wall of the vehicle.

SOURCE: need to know where the

4.6L, 5.4L & 6.8L Engines

  1. Disconnect the negative battery cable.
  2. Remove the accelerator control splash shield.
  3. Remove the Idle Air Control (IAC) valve electrical connector.
  4. Disconnect the throttle bypass hose.
  5. Remove the mounting bolts and the IAC valve.
  6. Installation is the reverse order of removal. Tighten mounting bolts in two steps:
    • Step 1: to 89 inch lbs. (10 Nm)
    • Step 2: an additional 90°

SOURCE: need to located the temperature sensor on 2002

The coolant temperature is measured from the cylinder head temperature sensor CHT and is located on the drivers side cylinder head in the rear. It is connected to the harness by connector C107 and has gray/red and yellow/light green wires going to pins 39 and 55 of the processor.

SOURCE: where is the temperature sensor located on a ford

The ECT (Engine Coolant Temperature) sensor is located either in the heater supply tube at the rear of the engine, or in the lower intake manifold. The ECT sensor is a thermistor (changes resistance as temperature changes).

The sensor detects the temperature of engine coolant and provides a corresponding signal to the PCM. From this signal, the PCM will modify the air/fuel ratio (mixture), idle speed, spark advance, EGR and canister purge control. When the engine coolant is cold, the ECT sensor signal causes the PCM to provide enrichment to the air/fuel ratio for good cold drive-away; as engine coolant warms up, the voltage will drop.

Hope this helps and keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment.

Have a nice weekend and thanks for using FixYa.
Jose.

2004 ford f150 5.4 3v idles rough but clears when rev engine up


Does you f 150 have electronic throttle control ? An does it have Variable Cam Timing (VCT) - if it does have Variable Cam Timing (VCT) it doesn't have an EGR valve ! What type scan tool did you use to pull the code with ? My FORD factory service information does not show that code for A 2004 F - 150 5.4 L 3 valve engine !

P0372 code


Possible causes


- Timing Reference Optical Sensor harness is open or shorted

- Timing Reference Optical Sensor circuit poor electrical connection

- Faulty Timing Reference Optical Sensor

- Damaged Powertrain Control Module (PCM)


What does this mean?



When is the code detected?


Some high resolution pulses are missing from the optical sensor to the PCM


Possible symptoms


- Engine Light ON (or Service Engine Soon Warning Light)


P0372 Description



The optical sensor provides a high resolution signal to the Powertrain Control Module (PCM) by counting pulses on the sensor disk located in the injection pump. The high resolution is one of the most important inputs by the PCM for fuel control and timing. This test monitors the number of high resolution pulses which have been missed (not detected). It's based on a comparison between the number of pulses that were detected since the last pump cam pulse and the number of the pulses that should have occurred. There are approximately 64 high resolution pulses for every cam pulse.

Operation

Specific to:
Ford Taurus 2008-2009
Mercury Sable 2008-2009
The Crankshaft Position (CKP) Sensor is a permanent magnet output coil device that monitors the speed and position of the crankshaft. A reluctor is attached directly to the crankshaft, and is used to generate a constant signal as it passes the CKP sensor magnetic coil. The CKP Sensor utilizes system voltage (12 volts DC), or reference voltage (5 volts DC) to generate a digital output signal to the PCM that is based upon a 0.5 volt AC reference. The alternating magnetic field is used by the sensor output electronics to produce a digital pulse. The CKP sensor returns a digital ON/OFF signal pulse during each revolution of the crankshaft, with a momentary signal interrupt for the top dead center (TDC) position of the #1 cylinder. The Pulse Width Modulation pattern is used by the Powertrain Control Module (PCM) to calculate ignition timing, fuel injector timing, misfire diagnostics, and the tachometer display

Honda accord incorrect gear ratio code p0370


Honda P0370 - Timing Reference High Resolution Signal A Malfunction.

The optical sensor provides a high resolution signal to the Powertrain Control Module (PCM) by counting pulses on the sensor disk located in the injection pump. The high resolution is one of the most important inputs by the PCM for fuel control and timing. This test monitors the number of high resolution pulses which have been missed (not detected). It's based on a comparison between the number of pulses that were detected since the last pump cam pulse and the number of the pulses that should have occurred. There are approximately 64 high resolution pulses for every cam pulse.

Possible Causes:
- Open or short in the optical sensor circuit
- Optical sensor connector
- Damaged optical sensor
- Damaged PCM
- Damaged ECM

Possible Solutions:
- If damaged repair the optical sensor circuit
- Replace optical sensor
- Replace PCM
- Replace ECM

Not sure where you got incorrect gear ratio. This P0370 DTC is for what I have listed above.

2004 escape where is the crank position sensor located?


We would recommend taking a look at the front of your motor, by either of the camshafts and where they exit the head(s). The sensor is either a optical or hall effect sensor, so try and find a housing that is near or around your intake or exhaust camshaft ( or just single camshaft) for the location of your camshaft position sensor

High idle stalls at lights code for crank sensor


Crankshaft and Camshaft Position Sensors Camshaft Position Sensor Engine timing is determined from the relationship between the crankshaft and camshaft. This relationship is maintained by a timing chain or timing belt. The Engine Management System does not control engine timing but it does monitor the relative position and speed of these shafts by monitoring signals generated by sensors. The Engine Management System (EMS) uses signals generated by the camshaft position sensor to synchronize fuel injection to the valve sequence and for the on-board diagnostic procedure for misfire detection. The EMS energizes the injector at or near the time the intake valve opens. For misfire diagnosis, the EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses Diagnostic Trouble Codes (DTC’s) should be stored in the EMS.
If the camshaft position sensor or circuit is faulty most engines will start. Some engine management systems will then default to a pre-programmed injector firing sequence. All injectors may be energized simultaneously or all of the injectors on one bank may be energized at the same time. If the CMP data is required for misfire detection and reliable CMP data is not present misfire detection would probably be suspended.
Related Symptoms The following symptoms can be caused by an intermittent wiring connection or faulty signal to the EMS:
  • Extended crank time with a cold engine
  • Intermittent rough running
  • Unstable idle
  • Bucking
  • Hesitation
  • Stumble
  • Chuggle
  • Poor fuel economy
  • Stalling on acceleration
Crankshaft Position Sensor Engine speed is a very important input to the Engine Management System (EMS). Crankshaft speed and position are the basis for many calculations made by the computer. Crankshaft position values are transmitted to the computer by pickup coils also known as Permanent Magnet (P/M) generators, hall-effect sensors or optical sensors. The Crankshaft Position Sensor (CKP) also known as engine speed sensor is located in close proximity to the crankshaft.
In addition the EMS uses minute variations in the CKP sensor data to determine engine misfire. The EMS uses this information in conjunction with the camshaft position sensor to perform misfire diagnostics.
Related Symptoms: No Start/Intermittent Start Condition – Can be caused by a faulty crankshaft position sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit
