  • Map sensor is likely stuck into the intake somewhere. The MAF is at the air box to air intake tube. If your getting a MAP sensor code I would check for a loose plug or for the sensor getting pulled out slightly. Could also be a sign your battery is getting weak. Although for me I got a bad throttle pedal sensor code when my battery was going bad.

Wow classic leveling zonesSep 26, 2010 · Manifold Absolute Pressure (MAP) Manifold Absolute Pressure (MAP) codes generally mean the MAP is bad, or there is a major vacuum leak. The MAP sensor is one major way the computer decides how much fuel the engine needs. Some cars have a stand alone MAP, some have a MAP sensor built into the MAF.

  • Thanks, I was kind of surprised it never threw a code before as bad as it looked, but I guess if it was continually relearning that would avoid that. My Jeep would throw codes with even a little gunk in the MAP sensor, but being a 2005 I'm sure it was a more primitive system.

they throw up fault codes for mass air flow sensor etc,, but reality is it tends to be the mass air flow and map sensor is working fine and has done its job,, ie warning of a problem before things start melting.. these valves go weak as early as 50.000 miles and some last 150.000 miles,, my theory is how hot the car gets and how hard driven may ... Reading and understanding the code information, as well as the Snap-On Troubleshooter, were key in repairing this fault. I also demonstrate how to safely clean an electronic throttle body, a very common feature on modern vehicles of all makes.

Apr 06, 2018 · At its core, an internal combustion engine is a vacuum pump. The pumping motion of the pistons causes a constant change of pressure in the intake manifold. The manifold absolute pressure (MAP) sensor monitors this and reports the information to the engine’s computer. If the MAP sensor starts to fail, these are some of the most common symptoms: 1.

P0108 is the code for a problem with the MAP electrical circuit sensor having too high voltage input to the Engine Control Unit (ECU). This means that the voltage input to the ECU is too high and that it is not in the correct range for proper engine operation to work with inputs from the Mass Air Flow Sensor (MAF) and Throttle Position Switch (TPS). A: In the 2002 Corolla, the code P0171 is often caused by a bad or dirty mass airflow sensor or vacuum leaks. Your mechanic can check for vacuum leaks and test the mass airflow sensor with a scan tool. If the mass airflow sensor is causing the lean condition, cleaning it may help, but usually, it will need to be replaced.

  • Apr 13, 2018 · I think I would try an ECT sensor, and then clear the code. See what happens. The ECM thinks the coolant is warm, so it is too lean for a colder engine. A mass airflow sensor will often have an intake air temperature sensor as part of the unit - the MAP doesn't. Your van has a separate sensor, but the scan tool doesn't show it.

When the P0171 code sets, the oxygen sensors are detecting too little oxygen in the exhaust (running "lean") and the control module is adding more fuel than normal to sustain the proper air/fuel mixture.
