SOURCE: check engine light on

P0700 - Transmission Control System Malfunction, this is a transmission or PCM issue and needs further diagnosis with other test gear.

The P1684 code simply means that the battery has been disconneted within the last 50 engine starts.

SOURCE: i have a 98 ford windstar 3.8 with a engine miss

I replaced the coil pack on my friends wind star when they had a mis. If you take the sparkplug wires loose and just set them on the plugs loose it will be easy to remove them with the engine running. Useing plastic plyers or some kind of insulated grabers, one by one take the wire away from the plug/or coil and see if it makes a difference.Take it away then put it back then go to the next one.If it runs the same when the wire is off then you probably will not hear a spark at that wire. The coils do go bad on alot of newer cars.
I hope this info helps you.

SOURCE: I have a 98 ford windstar with check engine light

These are all related:
P1537 and P1538 are BOTH:
Intake Manifold Runner Control Stuck Open
P0171 is Lean Bank #1
P0174 is Lean Bank #2.
On the front of the Intake Manifold there are Plastic Clips. The Clips are currently broken and need to be replaced. Because these are broke the Computer is registering too much Air or not enough Fuel = Lean.
You should be able to purchase these at any auto parts store (call ahead for availablility).
After you replace these, all the Codes should disappear.
Let me know if this helped, or if you have addtional information or questions. Feel free to contact me at FixYa.com!

SOURCE: My 2000 Ford Ranger keeps showing codes PO 171 and

These codes mean that the oxygen sensor is reading too "Lean" on both the left and right cylinder banks and the engine control system can't compensate any further to solve the problem. You may have a dirty or failing Mass Airflow Sensor that is miscalcuating the amount of airflow the engine is taking in which in turn can cause both of these codes to set. If the sensor is reporting less air than the engine is actually taking in then the engine computer will add only the amount of fuel it should based on what it was told by the sensor which will cause both cylinder banks to run "lean". There could be something else going on such as having two bad oxygen sensors [very rare] but I do see these two codes together quite often and usually its the sensor that is causing it. Hope this helps a bit!

Po316, po 300, po301, po305 2004 ford freestar


These codes are making me lean towards the ignition coil pack.My stepson's 2001 Sable 3.0 v6 had one cylinder misfiring(5-code P0305),which shares a coil with cylinder 1(code P0301).I diagnosed it by trading wire 1 and 5 at the coil,and the code changed to P0301.You have codes for the two cylinders on the same coil,so this is most likely it.(these codes would also trigger P0300(Multiple Misfires Detected) and P0316(Misfire Detected First 1000 Revs)).

2006 ford f150 dtc codes 401, 402, 607


It is very possiable that you may be getting a false code that will reocure till egr problems are repaired. The ecu may be trying to compensate for egr problems causing it to send the 607 code
