SOURCE: Cleaning the Mass Air Flow Sensor

i will try to help. 171/174 indicates lean condition in engine. the mass air flow sensor is located in the rubber tube going to throttlebody. you can try to clean it. using mild carb cleaner safe for sensors, remove sensor from tube. spray clean the tiny wires located in the cylinder. do not touch them, they are very delicate. these engines are also notorious for leaking intake gaskets and faulty pcv valves. these will all set these 2 codes. feel free with anymore questions.

SOURCE: installing chip and want to double check wiring. Need to find IAT/MAF sensor diagram for 2003 Ford Ranger

Save your money, the chip is a ohm resistor at Radio Shack for under $2.00. It splices in to you IAT wire harness located at the intake tube between the air filter housing and throttle body.
Problem with this system is, that you can not adjust anything and have to run a constant 91 octane just to make sure you do not have a Detonation. The ECM will catch the Detonation from the knock sensor and compensate for it by retarding the timing which in turn lose of HP till next start up.
If you like and don't mind the check engine light on once and awhile, you can do the same by just disconnecting the IAT wire harness which give the ECM a 0 resistance thinking it's -20 out side and turn the timing up and lengths the injector pules.
When i was running a Nitro in the Toy before i sold it, i had installed a 10K ohm Potentiometer which you can buy at radio shack for under $5.00 i believe, I just spliced it in to the IAC wire harness so if i wanted to play with the Nitro I'ld turn the resistor up making the engine think it's 185 degrees F and would ****** the timing so i would not hurt the engine. But if i wanted to get more timing i would just turn the knob to drop the resistance to get more time since the engine thinks it's -20 out side.
Hope this helps. Keep me posted if you need more info. Best thing is to do a dyno tune and you can change everything right down to the Shift points.

SOURCE: I have a 2005 ford ranger with 3 liter engine. I

take my advice, bro. When you're not 100% sure what the feedback had indicated, either the cam or the crank sensors. In my opinion, unless you are a professional mechanic having proper knowledge on the mechanics of this car, I would suggest you take the car to a dealer workshop and get it checked properly, because if you make a mistake and stuff the timing or interfer with the sensors and then it wont work as it should, you'll end up paying more than if you had the car serviced by a professional mechanic who specializes in this field, because these days cars have such delicate components and onboard computers, it is impossible to do the repairs yourself. This is no longer the 60-70's wehn you could fix a car yourself. Today, at the opening of your Ford's bonnet there is an intricate network of pipes, tubes, wires, anti-pollution monitors and other 'no-touch' componentry running to and from one end and another. So, to go ahead and do it youself, it would mean you first have to remove this 'component', then that 'bolt', and so on, eventually it will turn out you'll be stripping your engine and cannot recall what goes where. And, of course if you don't have the proper machines to monitor the cam dwell and timing, you'll further aggravate the problem. Although the repair manual tells you this and that but does it tell you the kind of machines and testing devices you'd need to test the sensors and or to reset the timing and cam dwell angle, or an oscilloscope to test other functions for a smooth running engine should you wish to do it yourself?

SOURCE: 2002 FORD RANGER 6CYL. 4.0L I GOT A P1400 TROUBLE

Exhaust gas recirculation flow insufficient detected.
Maybe you got a bad DPFE sensor, or the pintel inside the egr valve is not opening all the way causing the insufficient flow.

Code P1121 for TP sensor - where is it located on engine of 2002 4.0 ford ranger


P1121 - Throttle Position (TP) Sensor Inconsistent with MAF Sensor The PCM monitors a vehicle operation rationality check by comparing sensed throttle position to mass air flow readings. If during key ON engine running self-test the comparison of the TP sensor and MAF sensor readings are not consistent with calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.
  • Air leak between MAF sensor and throttle body
  • TP sensor not seated properly
  • Damaged TP sensor
  • Damaged MAF sensor
Drive vehicle and exercise throttle and TP sensor in all gears. A TP PID (TP V PID) less than 4.82 % (0.24 volt) with a LOAD PID greater than 55% or a TP V PID greater than 49.05% (2.44 volts) with a LOAD PID less than 30% indicates a hard fault.

Mapping codes P0107, P2263 & P2227 come up on scan tool what are these codes relating too? Ford Ranger 2008 not 2004 3.0 4 door


code p 0107 refers to manifold absolute pressure (MAP) sensor /barometric pressure (BARO) sensor --low input ====causes --wiring short to ground ---MAP sensor ---BARO sensor ---ECM
code p 2263 refers to turbo charger (TC) boost pressure /supercharger (SC) boost pressure ---performance problem====causes --mechanical fault
code p 2227 refers to BARO sensor -range / performance problem===causes wiring --- BARO sensor --- ECM
I would be testing the BARO sensor for a problem as it is listed for all 3 codes
if you don't have such a sensor you have a MAP sensor which is reading in the same area so test that as well

Get codes p0068 and p0108


codes p0068 refer to Manifold pressure sensor/mass air flow sensor--throttle position correlation--causes ---wiring---map sensor---maf sensor--mechanical fault.
code p0108 refers to manifold absolute pressure(map) sensor/barometric pressure (BARO) sensor--high input. causes ---wiring short to positive---map sensor---baro sensor---ecm.

Check engine light is on: engine idles rough


IT SOUNDS LIKE THE IAC (IDLE AIR CONTROL) MOTOR IS BAD OR GOING BAD, BUT THE QUICK SOLUTION IS GO TO ANY AUTO ZONE,OR ADVANCE AUTO PARTS STORE, AND THEY WILL CHECK IT FOR FREE,& TELL YOU WHAT SIGNAL CODE MADE THE CHECK ENGINE LIGHT COME ON, I WOULD DO THAT JUST TO BE FOR SURE, BECAUSE THERE ARE A FEW OTHER THINGS THAT CAN CAUSE IT AS WELL,SUCH AS MAF SENSOR DIRTY,OXY SENSOR GETTING A BAD READING,ETC.

Geting code po171 & po174


This is an indication that the PCV Elbow Hose is cracked or eroded. Also check the fuel filter.
Either of these 2 are faulty. Replace them, it will be solved.
Thank you Sir, Have a nice day.

2002 Ranger 4L v6 engine light stays on. Quick trouble shoot showed both banks were lean. What might be the cause?


A dirty Mass Air Flow Sensor (MAF) will cause and lean condition and also and dirty IAT will give you a lean condition. If you are using a oil charged air filter like K&N, droplet of oil will make there way to the MAF sensore and IAT causing them to give the wrong readings. You can buy a can of MAF sensor cleaner and clean both sensors. Make sure it's a MAF cleaner and follow the instructions. Good luck and hope this helps. Keep me posted, there are other reasons but this is the most common.
