My mass airlfow sensor is located between the filter and the throttle body. It is inline with the intake hose. This is in my experience the typical location for it. Itlooks like a ring around the intake hose with a box maybe 3"x3"x1" with a wire attached to it. Usually, if you detach the hose from the filter box, and look into the hose, you'll see a mesh grating. This protects the sensor from any debris in case anything were to get past the filter.
If you're very careful, sometimes you can clean the sensor elements and avoid replacing the sensor. Remove the sensor, remove the mesh and spray with a cleaner that leaves no residue (brake cleaner is good-- not carb cleaner) if necessary, gently wipe the sensor elements. They are fragile.
The thermostat on a 2000 Isuzu Trooper is located on top of the engine, below the upper radiator hose. It controls the flow of coolant to the radiator and throughout the vehicle.
EGR or Mass air flow sensor
You can use some carb cleaner, spray it on a rag and wipe it clean
Trouble code P0401 means:Exhaust gas recirculation flow insufficient detected
P0402, excessive EGR flow P1404, EGR range performance, valve closed Most of the time I find the EGR port in intake clogged. If you look in throttle body you will see a 3/8 tube plugged with soot. Clean and reset with scan tool.
no there is no kit. to check the fluid the truck must be level,warm and running. remove the top plug on the pan (which is on the pass. side)and fluid should flow out. its not easy.
It is located on the left side back for the engine looking from the front. Once u find it remove the two bolts and pull upward. Remove the gasget and use Carb cleaner to remove all the carbon deposits inside the EGR valve. This worked for me and i saved 110 dollars by not replaceing it. Works just like new.
The mass air flow sensor is located directly in the engine compartment. The MAF measures the temperature of the air and the amount of air entering the engine.
The blend door for a 2000 Neon is located behind the dash. The blend door controls the air flow for heat and ac.
located in the front right side conected to the air filter...
right next to Air filter box.
My 2000 rodeo 6cyl. Had same issue, Had to replace the EGR valve. This solved most of my issue, I was then instructed to Use Brakekleen and cleen the sensors in the Mass air flow sensor. Allow to fully dry before starting.
