Codes. 0307. O128. 0316. 1000. 2106.


P0307 = cylinder no.7 misfire detected.
P0316 = misfire detected during startup-first 1000 revolutions.
P0128 = coolant thermostat (coolant temperature below thermostat regulating temperature)
P1000 = On board diagnostic readiness test not complete.
P2106 = Throttle actuator control (TAC) system----forced limited power mode.

Check the spark plug, spark plug wire, coil, and fuel injector for cylinder 7. Check compression on cylinder 7. When the no. 7 misfire is solved, clear the codes.

The diagnostic test shows no signal from camshaft sensor. I checked all the wires for breaks, and I replaced the camshaft sensor code (0340). The car turns over good, but it will not start. Any ideas as to...


Cam sensor? or Crank sensor? I know that the generic definition of DTC P0340 is "No cam signal at PCM" however, a crank sensor can also be the cause of this code.

A cam sensor normally will not cause a no-start. I can cause a long crank time before starting. The cam sensor signal is only used to sync the fuel injectors. If there is no cam sensor signal the computer will start firing all of the injectors on every revolution of the crankshaft to get the engine running. A crank sensor, however, will cause a no-start condition because it is used to control spark. If there is no crank signal there is no spark...period.

Part of the troubleshooting chart for DTC P0340 on your vehicle includes inspection of the crank sensor and checking for the crank sensor signal at the Powertrain Control Module.

Ford escape 2005 having problems with revolutions, car seems to want to stop and then accelerates itself. We changed the number 2 spark plug relay as computer indicated however problem still persist.


There is no spark plug relay

You may have had a COP Ignition Coil,changed for #2, based on a PO302 code

What codes do you have now?

Sometimes the code won't tell you which coil is bad,if it is a bad spike,it will set a lot of wrong codes.

The PO300 Misfire, first 1000 Revolutions,you forget, means nothing to you.

You may have to buy a new coil and move it from one cylinder to the next,to find the bad one.

Unfortunately you have to remove the intake manifold, to do right bank coils

Hope your not still on 5 year old spark plugs. If so, remove intake,do plugs,install 3 new coils, on back cylinders and save them, to use on future coil issues or front bank,current problems.

Clean MAF Sensor (CRC MAF Cleaner)
Clean throttle plate (CRC Throttle Body Cleaner)
Meter out TPS Sensor----check for wear/inconsistant PCM feed back

Code p0301 and p0316


P0301 - Cylinder 1 Misfire Detected
P0316* - Engine misfire detected on Startup (First 1000 Revolutions) Could be a Bad Coil or bad spark plug or a bad wire on cylinder one. Check the plug and the wire first then move to the coil. Good Luck.

ERROR CODE 0340 AFTER TIMING BELT REPLACEMENT


Well either coincidence that the cam sensor went bad, you forgot to plug in the cam sensor, Or you have the cam that the sensor reads off of 1 tooth off. Check to see if its plugged in if yes remove the upper timing cover and see if everything lines up.
