2006 F150 cam shaft sensors, just replaced them and OBD2 still says they Bank 1 sensor A is intermittent ??? help


sounds like a wiring problem.

sounds like a wiring problem. you could run a temp. jumper wire from the ecm to the sensor and see if it goes away. if so run a new wire. that's what i'd do. mws919

thanks for your help, so out

thanks for your help, so out of the two wires running to the sensor, one goes to the ecm and the other would be a ground correct ?
is there an easy way to know what wire it is at the ecm besides using a schematic ?

one is a 5 volt referance

one is a 5 volt referance wire and the is the return. both go to ecm.

Man,sounds like im peeling

Man,sounds like im peeling some wires in the morning. thanks again

just use each wire from

just use each wire from connector to connector as a wire in a light bulb circuit. that way you can test the wire and the load it can carrie. rember any wire you cut and splice it must be protected from weather, any add. resistance to the wire will change it's reading. the best protection is heat shrink. radio shack.

will do, I want to just buy

will do, I want to just buy new heads, intake, and a carb, and just go out that way. but then im almost into the cost of just getting a crate engine !!

Bank 2 camshaft sensor A

Bank 2 camshaft sensor A circuit
is my only code now PO345
performed an OHMs test from the sensor
end and it checks out
ford won't get me in until next wednesday
i know you suggested a jumper wire, but i don't
know were the wires go on the ECM
any other suggestions ?

check wiring with a 12 volt

check wiring with a 12 volt bulb. resistance doesn't tell the amprges of the circuit. if a 12 volt head lamp will light brightly, you know you have a solid circuit. that's up to 15 amps. the only way to rule out the computer is to make sure all circuits and loads are 100%. i know with out wiring diagrams it's b#tch, but you can go by wire color code and a continuity tester. i donn't spend money on my cars, that's why i got into this, na, not realy, i'm 3dr. gen. in this. any way i think your best bet on this is to check out motoralldata.com for one mo. you'll get all the answers for your truck. it's about $25.00 a mo., for one car/truck. good deal, when the dealer charges about $90.00 an hour. let us know how you make out. mws919

the truck runs rough and

the truck runs rough and rich, pulled the bank 2 sensor when it is running and no change, which means its not even working. checked the voltage on the wires, both read 4 volts. i will check with a 12 volt light.

pulled bank 1 when it was

pulled bank 1 when it was running, no change.
my mistake....they don't read 4 volts, both banks of wires read .04 volts. 56k on the motor, had a complete service at 30k, im starting to think its just plugs and coils.

on that same note, you think

on that same note, you think my Variable timing gear could be stuck on that bank ?

i thing the voltage for the

i thing the voltage for the sensors is around 5 volt. do you mean 56k ohms across the injector? if it is a circuit code, it's not coils or plugs. if vvt system had a falt, it would set a code. your voltage sounds low. check each wire to ground with key on and let me know the voltage.

OKAY, I checked the voltage

OKAY, I checked the voltage off both sensors(bank 1 and bank 2) they read .04 volts. pretty much no voltage at all unless we go into millivolts. the truck had to be running to get this reading. what is troubling is that my fault code is for bank 2, and not for bank 1, yet I am getting the same voltage off both sides ??

both sensors will have a wire

both sensors will have a wire that is the same color. now on the sensor that set the code, check the diff. colored wire from the sensor connector to the same color wire in the computers connector. use this wire in a circuit connected to a 12 volt bulb and connectit to the batt. if the bulb is dimmer than when it's put acrossed the batt. then you got a bad sensor return wire. the diff. colored wires to the sensors are what the computer uses to know witch is witch. try this and let me know.

taking it to ford in the

taking it to ford in the morning, thanks for all your help it made a big difference.
i will let you know what there diagnosis was tomorrow.....
thank again
