The crank sensor is easy there is no re-set get a new one. If that doesn't fix it take it back and put the old one back in. As far as reseting the security on this vehicle no legit person over the internet can give you this info. legaly. However if you are losing inj. signal check the computer and module.

SOURCE: 97 Jeep grand cherokee 6 cyl. idles down to 0 and dies.

any leaks in intake or exhaust upstream of the sensors, sparkplug condition and engine controls/sensors for out of range operation (including fuel pressure and condition of regulator)
IAC should be cleaned and checked as this can cause poor idle and shut down. I'm not saying not to change O2 sensors, but unless everything else if OK, it probably won't help.

SOURCE: 4.3 vortec runs OK cold, runs rough or dies warm

Your cylinder 4 misfire would most likely be a bad plug wire. And it is common for cars to have driveability problems with a crankshaft sensor code, esspecialy after the car has warmed up that is when you will notice the problem. The crank sensors are pretty simple to change and relativley inexpensive maybe around 40.00 for the part. If you look around the crank shaft pulley you will see a sensor with usually 2 bolts and a couple of wires attatched to it. If the vehicle gets to a point that it won't start, spin the motor over watching the tach on your dash and if it is not moving while cranking that means the sensor gave out. Good luck.

97 ford escort p401 code

You may have carbon plugging the passages on the intake side of the valve. Remove the valve and start the engine. It should die or run very rough. if it idles normal then you have blockage that needs to be cleaned out.

First take the mass air flow sensor off and clean the small thin wires inside using a non-chlronated brake cleaner then let it dry for 10 minutes then re-install it and see if the problem still exist.If the problem still exist then check the fuel pressure while its running. It should be 30-40 psi if its the 3.8 engine non-superchared and 30-45 for the 5.0 engine.If its not within these specs then replace the fuel pump.

Ford taurus dpfe sensor hose blowing off

I have to put thus little bit of info in here. I just had to deal with an 02 Taurus that would not start. Managed to get it to start by holding the gas pedal to the floor and when it finally fired up it blew the DPFE hose off. After a while of it sitting in the garage I decided I would just keep the gas floored and after a few seconds it came around. My suspicion is that because this car only runs for a few minutes at a time, moisture accumulated in the CAT and froze when temperatures got into the single digits. My conclusion is make sure the vehicle get to operating temperature during cold weather to prevent exhaust freeze-up.

I have a tropubleshooting code of P1405. On a ford Expedition 5.4l. Where do i fine the DPFE sensor (DPFE sensor upstream hose off or plugged.. aaECM detected EGR flow in a negative direction with aan

DPFE sensor failures are VERY COMMON on Ford vehicles. However, clogged EGR ports are also very common on 5.4L Ford engines. The DPFE sensor is located on the left side of the engine. It connects to two silicone rubber hoses that connect to the steel EGR tube coming from the back of the engine to the EGR valve. (See picture of the sensor below)

Another common failure is a DPFE sensor that has melted due to excessive exhaust back-pressure. If you find the DPFE sensor melted, suspect a restricted exhaust. (smashed tailpipe, clogged catalytic converter, etc..)

Battery wont stay charged alternator replaced and starter 1994 ford thunderbird

Depending on the age of your battery you should probably have it load tested. A battery with a bad cell can get what we call a surface charge. This is only good for a few minutes and it dissipates indicating a bad cell in the battery. If you loose a cell you loose two volts and that is enough to not let your vehicle start. The average battery lasts about 4 years if it is a good one. You get what you pay for in batteries. Lower priced battery equals less service out of it over the long run. Extreme hot and cold weather wreak havoc on batteries that are a few years old.

Why does our 97 ford f-150 4x4 rev up on rpms to over 4000 all by itself every few seconds ? then it quits and will run fine again for miles? why?

That would be your EGR valve and dpfe sensor. The hoses that connect to the dpfe sensor might need to be replaced or the sensor itself. If the two little blak hoses are bad you will have to get them from a dealer because of the high temp running through the EGR Valve tube. Both control idle speed.

I am having trouble getting my check light to go off after I had it checked and the EGR valve was replaced. The light comes back on after about 15 miles of driving and the code reads EGR poor flow. I can...

Insufficient EGR Flow Detected

Possible Causes:
DPFE sensor signal circuit is shorted to ground
DPFE sensor VREF circuit is open between sensor and PCM
DPFE sensor downstream hose off or plugged
DPFE sensor hoses both off, loose or damaged
DPFE sensor hoses connected wrong (reversed)
EGR orifice tube is damaged or restricted
PCM has failed
And what sets the code is…….Engine started, engine running in closed loop under steady cruise conditions, and the PCM detected the DPFE sensor input indicated insufficient EGR gas flow. Run the KOER Self-Test, and if DTC P1408 is present, the fault is currently present. This code sets in 2 Trip(s). The light will stay on until the cause is repaired. A bad EGR valve is only on possible cause.

Hope this helps,
