If it has one it would be between the air filter and the throttle body. I don't show a part number for a 6 or 8 cyl Grand Cherokee.

try spray cleaning your air mass sensor. be careful and use very little spray. you can damage the air mass sensor with too much spray. the air mass senser tells the computer if your air filter needs to be replaced. it is located between the air filter and the air throttle body.

P0101: MAF or VAF A Circuit Range/Perf

- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection
- Intake air leaks
- Faulty mass air flow sensor

Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.

Location of the Mass Air Flow Sensor? And how to clean it?

Hi, the mass air flow sensor is on the intake tube just before the throttle body. these sensors are extremely sensative. there is a special cleaner that you can purchase at parts stores.

Problem starting 1999 escort. has fuel, spark, timinging is dead on the money. acts like it will start but wont

Check the air mass meter or air mass sensor, also the crack sensor can cause this fault.

EGR valve but the car will normally still start with that fault. most common is the air mass sensor, you can just try and clean it first and check the wires to the sensor its most likely the air mass sensor or air related fault.
