General Lee: For such a TSP platform, indeed, is the test of the ability to integrate the same time, just She always has been mentioned in the business platform is a completely independent intellectual property platform and our platform is t In the shape of the design, the Core wing broke through the traditional appearance of the other models, the Core-wing sense of movement and high-level sense of the high degree of balance, which must be improved, both in the interior styling
Manifold absolute pressure (which short forMAP) sensor of car is located on the front portion of the Neon's air intakemanifold and has two small screws securing it into place. MAP sensors areresponsible for identifying the air pressure within the manifold and sending areading to the engine's ECU (engine control unit) referring to the voltagelevel for the spark in the ignition cylinder. If your MAP sensor is malfunction,you will notice a reduction of power, backfiring and hesitation whenaccelerating. It is very important to first test related engine componentsbefore replacing the MAP sensor.You'll Need OBD 2 scanner, Gaffer's tape, Multimeter,Screwdriver and Socket wrench set for this job.Insert an OBD 2 scanner into your Neon'sOBD port; it is generally located to underneath your steering column near thedriver's door. The OBD port will usually be within 2 to 3 feet of the steeringcolumn on any car manufactured after 1995. Power on the scanner and turn theNeon's ignition key to the accessories position. If your scanner cannottranslate the troubleshoot code, then you will need to consult it on a websitesuch as OBD Codes or by search engine.Check your air intake assembly and vacuumlines leading from the intake to the manifold for leaks and unplugged joints. Powerthe engine on and feel around the vacuum hoses attached to the manifold for anyspurting of pressurized air. Use gaffer's tape to plug up and secure any leaksor disjointed lines that are leaking. Also check the air filter for verydirtiness and replace it if necessary. If you do any repairs to the intake, youwill need to erase the OBD code using your scanner and drive your Neon for atleast 25 milesso as to make sure that your MAP sensor will not activate the check enginelight again.Check the MAP sensor's electricalconnection by using a multimeter or voltmeter. Unplug the electrical connectionleading to your MAP sensor. The electrical connection should read between 4.5volts and 5.0 volts when the engine is turned on and the probes are touchingthe terminals on the electrical connection. If the terminals do not read thecorrect voltage, or if they are completely dead, then you may have anelectrical problem but not a failed MAP sensor.Replace the MAP sensor by unscrewing itfrom the air intake assembly. Unplug the electrical connection. Screw in thenew MAP sensor with a screwdriver or socket wrench. Connect the electricalconnection again. Using the OBD scanner to erase the MAP sensor troubleshootcode. I am glad to communicate with you, if you are interested in OBD 2scanner. Article Tags: Electrical Connection
