P0016 fault code

I'm hoping someone can shed some light on a problem my mum has with her 57 plate 1.3 VVTi (manual) Yaris The engine light came on so I looked on the internet and someone suggested it could be as simple as the petrol filler cap wasn't on tight enough so I looked at this and the light went off. Shortly after this it came back on so I disconnected the battery for half an hour which also worked briefly but now the light is on continuously and the petrol cap is tight. She took it to her local garage who charged 50 pounds to plug it in to their diagnostic equipment and it came back with the following (and this is word-for-word): 2 Fault Fault Codes: P0016 CAMSHAFT-/CRANKSHAFT POSITION BANK 1 SENSOR A - IMPLAUSIBLE RATIO Fault Codes: P0016 CAMSHAFT-/CRANKSHAFT POSITION BANK 1 SENSOR A - IMPLAUSIBLE RATIO They said it was showing two faults (both the same) as it failed twice during the test. One mechanic said it could be problem with a stretched cam (timing) chain. Another said it was most likely the Oil Control Valve. I've replaced this but after re-setting the light it's now come back on. The car runs absolutely fine with no misfire or rough running. The oil has been changed fairly recently so it's unlikely to be this. Please could anyone shed any light on this? I'm thinking next best thing to do is to replace the cam sensor? I don't want my mum to keep throwing money at this without getting to the root of the problem.

Try first unplugging battery cable for ten minutuse, to reset ECM, and do a scan again, there are too many unrelated error codes at the same time

SOURCE: 06' Ford Explorer engine light wont go off after repair

Yes, that sounds correct to be calibrated.and probably is what is causing your problem. Mass air flow sensors hardly ever go bad. They get dirty and set a code. Garages will try to sell you one when you can clean it with a throttle body cleaner. If you have your old one, clean it and put it back on, try it to see if it works better.

SOURCE: 1995 Windstar OBD II showing codes PO340, PO171, and PO174.

Symptoms of a faulty Camshaft Position Sensor can include hard starting (or no starting), rough running/misfiring and/or loss of power.

Code 340 COULD be caused solely by a faulty Camshaft Position Sensor. However, this code refers to the entire circuit. So, replacing the sensor may not fix the issue. The problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM.

Codes 171 and 174 typically appear together. They are caused by the 02 sensors reading too much air (lean) in the exhaust. In most cases, simply cleaning the MAF sensor does the trick. I typically take it off and spray it with electronics or brake cleaner. Just make sure it dries before reinstalling. If this doesn't eliminate the codes, inspect all vacuum and PCV hoses, check for a dirty fuel filter and ensure the furl pressure is within limits.

For clarification, the first trip to the shop your car showed codes 402, 732, 733, 171 and 174. After changing the DPFE/EGR, did ALL those codes go away and now only codes 340, 171 and 174 exist? Or do you have the second set of codes in addition to the first codes?

the computer may need to be reflashed. if it is running then it is not a bad sensor. either of those being bad would cause it not to run.

I think your sensors are pattern parts and the readings /resistances are not the same as the original parts ,try some bosch units is my first suggestion ,
