Where is map senser located

I don't list a map sensor being used on a 1987 Olds with the 3.8 engine. It should have a MAF sensor instead.

1999 olds 88. I have replaced the fuel pump, sending unit, filter, mass air flow senson, spark plugs and wires, fuel pressure regulator. The car idles fine but when you apply pressure to the gas pedal it...

recommend you check your MAP sensor. You will need a voltmeter.
If you don't have a vacuum gage, just use your mouth to pull a vacuum on the hose and see if the voltage drops when you do.
Let me know if you have questions.

OPERATION The Manifold Absolute Pressure (MAP) sensor, used on 1996-99 vehicles, measures the changes in intake manifold pressure which result from engine load/speed changes, and converts this information to a voltage output. The MAP sensor reading is the opposite of a vacuum gauge reading: when manifold pressure is high, MAP sensor value is high and vacuum is low. A MAP sensor will produce a low output on engine coast-down with a closed throttle while a wide open throttle will produce a high output. The high output is produced because the pressure inside the manifold is the same as outside the manifold, so 100 percent of the outside air pressure is measured.
The MAP sensor is also used to measure barometric pressure under certain conditions, which allows the PCM to automatically adjust for different altitudes.
The MAP sensor changes the 5 volt signal supplied by the PCM, which reads the change and uses the information to control fuel delivery and ignition timing.

TESTING See Figures 1 and 2

  1. Visually check the connector, making sure it is properly connected and that all of its terminals are straight, tight and free of corrosion.
  2. With the ignition ON , check the voltage between terminals A and B (probe the back of the connector to connect to these wires). It should be above 4 volts. Apply 15 in. Hg of vacuum at the MAP vacuum port and check the voltage again. The voltage should be 2 volts now.


Fig. Fig. 1: Manifold Absolute Pressure (MAP) sensor circuit
When pumping up and releasing the vacuum, check to make sure the voltage readings are smooth. When applying vacuum to the sensor, the change in voltage should happen instantly. A slow change in voltage could point to a faulty sensor.


Fig. Fig. 2: MAP sensor voltage specifications

  1. If the sensor voltage is not within specification, check for a 5 volt reference at terminal C. If the reference signal is found, the sensor is faulty.
  2. If the sensor and circuits are functional, the PCM may be faulty.


3.8L (VIN K) Engine
See Figure 4
On these engines, the MAP sensor is mounted to the PCV valve cover.

  1. Disconnect the negative battery cable.
  2. Detach the MAP sensor electrical connector.
  3. Carefully bend the locking tabs holding the MAP sensor to the PCV valve cover, just enough to remove the MAP sensor.
  4. Pull the MAP sensor straight out of the PCV valve cover.

Fig. Fig. 4: On the 3.8L (VIN K) engine, the MAP sensor (1) is mounted in the PCV valve cover (2)

To install:

  1. Make sure that the seal is installed on the MAP sensor and that it is not damaged.
  2. Position and install the MAP sensor to the PCV valve cover. Make sure the locking tabs engage to hold the sensor to the cover.
  3. Attach the sensor electrical connector.
  4. Connect the negative battery cable.

Where is the MAP located on a 87 olds delta 88? is it on the firewall?

I have a series II 3.8 liter. The MAF sensor is located under the plastic cover for the engin. You have to take the oil fill cap and neck off to lift the cover off. Once the cover is removed, the MAF sensor can be seen at the top and to the left of the engin. it is a small square box that has a three wire plug in and two vacume lines going to it. Ceck to see if the wire connections are ok before you replace the sensor. Good luck.

Bucking engine

Check the fuel pressure,also change the fuel filter.check the crankshaft sensor,or replace.It sounds more like the tps sensor(throttle position sensor).It is mounted in line with the throttle axle,on the throttle horn.Of course .with out being there and checking I am just guessing.But map sensor or mass air flow sensor could also cause this.Have you checked the air filter?This will cause the problem,if it is stopped up restricting air flow to engine and mass air flow.,map sensor,and vacuums needed to run the car.If I can help,let me know.

check your wiring for dirty connections or broken wires, you may have wires that are rubbed through or connectors that are not making full contact. you will need an ohm meter and check wires for continuity. a wiring diagram will be needed.
