your map sensor is fine , there is a short somewhere so your ecu is not reading it your map sensor is fine , there is a short somewhere so your ecu is not reading it
Yes, but first you need to know the min and max ohm reading the sensor operates between. Service schematic of wiring and sensors will provide this info. It may be difficult to tell if it is operating correctly, however it would let you know if the sensor is completely shot. (Ohms will be out of range)
It appears that all that you can test is the resistance across the sensor. Testing across terminals +b and HT at 20 degrees centigrade (68 degrees Fahrenheit) the front sensor (Bank 1 sensor 1) should give a a reading of 5~7 ohms, the rear sensor (bank 1 sensor 2) should return a reading of 11~16 ohms. Readings outside this range suggest replacing the sensor.
The MAP (manifold absolute pressure) sensor monitors the intake manifold pressure changes and adjusts the fuel delivery based on its reading
It uses a MAP sensor.It uses a MAP sensor.
Find out the ohms range it must be within and do an ohms test.
you prob. have a bad map sensor. to test map sensor, put the + lead from a dc meter on the center wire that hooks up to the map sensor and the - lead to ground, you should get a reading between .5-4.5 volts any thing below or over map sensor is bad
yes the map sensor will keep the car from running.map stands for manifold air pressure and if the ecu cant get a reading it will not start and run.
Change in MAP sensor reading beyond limits.
a map sensor is a manifold absolute pressure sensor.
if it has a 3.3 there is no map sensor
