MAP (Manifold Absolute Pressure) sensor

This may be a sign of a faulty MAP sensor. The Manifold Absolute Pressure (MAP) sensor senses engine load and generates a signal that is proportional to the amount of vacuum in the intake manifold. The engine computer then uses...

Hello. MAP stands for manifold absolute pressure. So the answer to your question would be that it is the manifold absolute pressure sensor that there is something wrong with. The map sensor reads the pressure in the manifold and sends...

Hello. In order to know why the light is on (https://www.yourmechanic.com/article/the-check-engine-light-demystified), I would need to know the codes from the computer. It can be anything for a computer issue to a bad gas cap. I usually scan the computer first...

Yes a MAP sensor can cause this problem. The sensor controls how much load is on the engine and will cause the rich running condition. I have never known one that can be cleaned and fix the problem. I recommend...

Hi there - the MAP (manifold absolute pressure) sensor (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-manifold-absolute-pressure-sensor-map-sensor) is located midway, on the top of the straight, "tube-like" portion of the intake manifold. This "tube" sits above the "octopus-like" 4 air tubes into the engine. It is attached...

Hello. There is only one MAP sensor on your vehicle. If you replaced it and the code has not gone away, or you are still experiencing the same symptoms, there is likely something else going on with the circuit. Make...

Hello, thank you for writing in. On your particular vehicle, the MAP (manifold absolute pressure) sensor is located on the firewall. This is why they refer to it as a "firewall mounted MAP sensor". The firewall is the wall between...

Hi There, Based upon what you are describing and how the car responds to load, it sounds like you may have a faulty MAP sensor. The Manifold Absolute Pressure (MAP) sensor senses engine load and generates a signal that is...

It sounds like you may have a faulty MAP sensor. The Manifold Absolute Pressure (MAP) sensor senses engine load and generates a signal that is proportional to the amount of vacuum in the intake manifold. The engine computer then uses...

The internal transmission seals are leaking pressure to reverse and forward gears at the same time and lock up transmission then stalls the engine. You will need to have a pressure test on the transmission to see if the leak...

No. The MAP sensor is more than a sensor inside the case, as it contains circuitry that may alter the output voltage as specified by manufacturer needs. If you need help getting the correct part, YourMechanic can source and replace...

This suggests that the low idle problem may be related to a faulty MAP sensor since the symptoms you describe point to the low idle issue when the engine is under a load when applying the brakes at idle. The...

Besides the MAP sensor code, you may have a transmission major failure or a problem with the shift cable (https://www.yourmechanic.com/parts/automatic-transmission-shift-cable). The shift cable bushings wear out and these vehicles sometimes the cable will pop off of the shift linkage of...

Hello, thank you for writing in. The most likely cause of the issue is a bad MAP sensor. Before changing it out, you will want to check for any other obvious signs of problems. These would include frayed or damaged...

Hello - the Manifold Absolute Pressure (MAP) sensor (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-manifold-absolute-pressure-sensor-map-sensor) is located on top of the intake manifold, in the middle. This will be between the valve cover and the firewall that separates the engine compartment from the passenger compartment. It's...

If you are getting a reading of 89HZ out of the MAP sensor with the key on then this is an indication that you are above 15,000 feet in elevation. This would cause the computer to run your vehicle with...

Hello - the MAP sensor (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-manifold-absolute-pressure-sensor-map-sensor) is located on the intake manifold, near the back. It has a flat, 3-wire electrical connector. For assistance, I recommend a MAP sensor replacement service (https://www.yourmechanic.com/services/manifold-absolute-pressure-sensor-map-sensor-replacement) by a mobile, professional mechanic, such as one...

It sounds like you may have a fuel supply issue that corresponds to the load put on the motor when you turn the A/C on. This may be related to a faulty MAP sensor. The Manifold Absolute Pressure (MAP) sensor...

Due to the change in load put on the motor when shifting into gear vs neutral and the change in load when the a/c is on vs not on, this may suggest you have a bad MAP sensor. Both of...

Hi there. Trace the wires to the bulk wiring harness and check continuity from the wire to the end of the plug. If there is resistance, then disconnect the battery and remove the wiring harness from the computer and check...
