About an Ford Ranger or B2300 Mazda DTC

Good afternoon, the fault that your truck presents is in the exhaust gas recirculation system reviews escape connections with leaks, obstruction of the valve-solenoid tube, wiring of the harness harness of the damaged sensor, the recirculation valve of the damaged escape, ho check the engine computer but by my experience it is the valve that does not serve does not feat the truck. Foquito de Check Engine there you have your problem solved I hope and I have served my comment I am pending for a future consultation thanks

Hello smiling 762 verify EGR solenoid mangas and everything is bn now I am ringing the DTC P1400

That code is manufacturer and is (differential pressure feedback EGR circuit low input) you have problems with the EGR system you have to change that EGR feedback

Well, the DTC erased and now this more P1443 appeared and the other two that I already gave me that it was the P1400 and the P0401 thanks if you can help me and more Hawk that EGR feedback is the solenoid that has the two sleeves ????

The whole problem comes from the same. If that is the sensor that has two sleeves check with an empty rack to see what reading teda since they can have there problems.
The stable reading between 17 and 22 in HG, with the hot engine and minimal launch is correct.
If the needle lows almost zero when accelerating the engine, and then rises almost to the normal level; Indicates that the escape system may be obstructed.
A high and stable reading greater than 21, indicates a restriction at the air entrance. The air filter can be clogged by dirt or oil. Or that the acceleration plate is attached by dirt.
