If you have the 4.0 six then look at the front of the engine and follow the top radiator hose from the radiator to the thermostat housing at the engine. nest to the housing look to the right and you will see a sensor that screws into the head next to the housing. This will be the temperature sensor.

OPERATION

See Figures 1, 2 and 3


0900c1528003c4d9.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 1: MAP sensor location-2.4L engine


0900c1528003c4da.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 2: MAP sensor location-3.0L engine


0900c1528003c4db.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 3: MAP sensor location-3.3L and 3.8L engines
The PCM supplies 5 volts of direct current to the Manifold Absolute Pressure (MAP) sensor. The MAP sensor then converts the intake manifold pressure into voltage. The PCM monitors the MAP sensor output voltage. As vacuum increases, the MAP sensor voltage decreases proportionately. Also, as vacuum decreases, the MAP sensor voltage increases proportionally.
With the ignition key ON , before the engine is started, the PCM determines atmospheric air pressure from the MAP sensor voltage. While the engine operates, the PCM figures out intake manifold pressure from the MAP sensor voltage. Based on the MAP sensor voltage and inputs from other sensors, the PCM adjusts spark advance and the air/fuel ratio. The MAP sensor is mounted to the intake manifold, near the throttle body inlet to the manifold. The sensor connects electrically to the PCM.


TESTING

See Figures 4, 5, 6 and 7


0900c1528003c4dc.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 4: Disengage the MAP sensor connector-3.0L engine shown

WARNING When testing the MAP sensor, make sure the harness wires do not become damaged by the test meter probes.

  1. Visually check the connector, making sure it is attached properly and that all of the terminals are straight, tight and free of corrosion.

Fig. Fig. 6: MAP sensor connector terminal identifications-2.4L, 3.3L and 3.8L engines


0900c1528003c4df.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 7: Using a digital volt-ohmmeter, test the MAP sensor voltage-3.0L engine shown

  1. Test the MAP sensor output voltage at the sensor connector between terminals B and C (2.4L, 3.3L and 3.8L engines), or A nd B (3.0L engine).
  2. With the ignition switch ON and the engine not running, the output voltage should be 4-5 volts. The voltage should fall to 1.5-2.1 volts with a hot, neutral idle speed condition. If OK, go to the next step. If not OK, go to Step 5.
  3. Test the PCM terminal 36 for the same voltage described in the previous step to make sure the wire harness is OK. Repair as necessary.
  4. Test the MAP sensor ground circuit at the sensor connector terminal A (2.4L, 3.3L and 3.8L engines) or C (3.0L engine) and PCM terminal 43. If OK, go to the next step. If not OK, repair as necessary.
  5. Test the MAP sensor supply voltage between the sensor connector terminals A and B (2.4L, 3.3L and 3.8L engines) r A and C (3.0L engine) with the ignition key in the ON position. The voltage should be about 4.5-5.5 volts.
  6. There should also be 4.5-5.5 volts at terminal 61 of the PCM. If OK, replace the MAP sensor.
  7. If not, repair or replace the wire harness as required.


REMOVAL & INSTALLATION

See Figures 1, 2, 3 and 4
The MAP sensor is mounted on the intake manifold near the throttle body inlet to the manifold.

  1. Disconnect the negative battery cable.
  2. On the 3.0L engine only, disconnect the vacuum hose from the MAP sensor.
  3. Detach the electrical connector from the MAP sensor.
  4. Unfasten the mounting screws, then remove the MAP sensor from the vehicle.

To install:
  1. Install the sensor onto the intake manifold and tighten the mounting screws to 35 inch lbs. (4 Nm).
  2. Attach the sensor electrical connector.
  3. On the 3.0L engine, connect the vacuum hose to the MAP sensor.
  4. Connect the negative battery cable.

Sending Units and Sensors
REMOVAL & INSTALLATION
Engine Coolant Temperature
On all vehicles covered by this manual an Engine Coolant Temperature (ECT)
sensor can be found threaded into one of the engine coolant passages. The sensor
is a thermistor (a resistor which changes value based on temperature) and is
used on all computer controlled fuel systems to help regulate fuel and emissions
systems controlled by the computer module. The sensor may be found in various
places on the engine. Most engines will likely have this sensor threaded into
the intake manifold, often near the thermostat housing.





Fig. 1: On most vehicles such as the 4.3L (VIN Z) engine, the
coolant temperature sensor is mounted in the intake manifold
85383037.gif

NOTE: Care must be taken when handling engine control related
sensors as damage to the sensor may adversely affect engine driveability and
emissions.



  1. Disconnect the negative battery cable.
  2. Drain the engine cooling system to a level below the sensor.
  3. Release the locktab and disengage the sensor connector.
  4. Using a special sensor tool or a deep 12-point socket, loosen the sensor,
    then carefully unthread and remove it from the engine.
    To install:

  5. Thread the sensor into the engine by hand, then tighten using the socket or
    tool. If a replacement sensor came with instructions use a torque wrench to
    assure proper tightening.
    NOTE: On some engines, such as the Syclone's MFI 4.3L engine,
    the manufacturer suggests coating the coolant sensor threads with a sealant such
    as 1052080, or equivalent.



  6. Engage the sensor wiring harness.
  7. Connect the negative battery cable.
  8. Properly refill the engine cooling system, then run the engine and check for
    leaks.

Manifold Absolute Pressure (MAP) Sensor
The MAP sensor measures changes in the intake manifold pressure, resulting
from changes in engine load and speed changes, then converts this to a voltage
output. Other than checking for loose vacuum hoses or electrical connectors, the
only service possible for this sensor is replacement, if testing shows the
sensor is faulty.

  1. Disconnect the negative battery cable.
  2. Release the locktab, then disengage the sensor electrical connector.
  3. Either tag and disconnect the hoses from the MAP sensor or disengage the
    entire vacuum harness assembly from the sensor, as applicable.
  4. Either remove the retainers or release the lock tabs, then remove the sensor
    from the engine.
    To install:

  5. Install the sensor and secure in position using the retainers or lock tabs,
    as applicable.
  6. Connect the vacuum harness or hoses to the sensor as noted during removal.
  7. Engage the sensor electrical connector.
  8. Connect the negative battery cable.

Oxygen Sensor
Almost all vehicles covered by this manual were equipped with an oxygen
sensor for feedback carburetor control . Fuel injected engines, introduced to
the S/T series in 1985 and used on all of these trucks built in 1986 and later
also require an oxygen sensor for computer air/fuel mixture management. On
vehicles so equipped, the oxygen sensor is usually mounted in an exhaust
manifold. On some engines, the sensor is mounted at the end of the crossover
pipe.

  1. Disconnect the negative battery cable.
  2. Locate the oxygen sensor. The sensor is usually mounted in the exhaust
    manifold or in the crossover pipe. If necessary, raise and support the front of
    the truck safely using jackstands.
  3. Trace the wires leading from the oxygen sensor back to the first connector
    and then disengage the sensor harness connector.
    NOTE: The sensor may be extremely difficult to remove when
    engine temperature is below 120°F (48°C). Be careful as excessive force could
    damage threads in the exhaust manifold or pipe.



  4. Using a special sensor tool or a socket, loosen the sensor, then carefully
    unthread and remove it from the engine. If sensor removal is difficult, spray a
    small amount of commercial heat riser solvent onto the sensor threads and allow
    it to soak in for at least five minutes, then attempt to loosen and remove the
    sensor again.
    CAUTION
    Avoid using cleaning solvents of any type on
    the oxygen sensor. Keep the louvered end free of grease, dirt or other
    contaminants. Do not drop or roughly handle the sensor. If any of these cautions
    are ignored, the sensor could be damaged resulting in poor engine performance
    and excessive exhaust emissions.
    To install:

  5. New oxygen sensors will be packaged with a special anti-seize lubricant
    already applied to the threads. If a sensor is removed from the exhaust and is
    to be reinstalled for any reason, the sensor threads must be coated with a fresh
    anti-seize compound. Use a G.M. anti-seize compound no. 5613695, no. 3613695 or
    an equivalent compound made of liquid graphite and glass beads. This is not a
    conventional anti-seize paste, the graphite will tend to burn away but the glass
    beads will remain. The use of a regular compound may electrically insulate the
    sensor, rendering it inoperative. You must coat the threads with an electrically
    conductive anti-seize compound.
  6. Carefully thread the sensor into the exhaust bore, then tighten to 30 ft.
    lbs. (41 Nm) using a torque wrench.
  7. Engage the sensor harness.
  8. If raised, remove the jackstands and carefully lower the truck.
  9. Connect the negative battery cable, then start and run the engine to check
    for proper operation.

The crankshaft sensor is an important sensor for regulating spark and fuel injection pulsing.

I don't know what an 'engine sensor' would be besides the crankshaft sensor, specifically.

Engine sensor is a general term.

How to repalce a knock sensor on my 2004 gmc yukon


Hi welcom to fixya. A defective knock sensor may cause engine detonation or reduced spark advance and fuel economy. When a knock sensor is removed and replaced, the sensor must be tightened to its specified torque. If the knock sensor is installed tighter than it should be, it may become too sensitive and provide an excessively high voltage signal, resulting in more spark ****** than required. When the knock sensor is installed looser than it should be, the knock sensor signal will be lower than normal, resulting in engine detonation.
To replace the knock sensor:
  • Disconnect the knock sensor wiring connector.
  • Then, unscrew the sensor.
  • Remove the knock sensor.
  • Reverse the procedures to install the part.
  • 15 ft.lbs.torque
  • hope this helps.Thank You for using fixya..iluv2fish.. Ray..
