Have a colleague who has a 1.3 2007 Yaris that has the CEL light on constantly, my Autocom identifies the fault code as "P0016 - Crankshaft position - camshaft position correlation - Bank 1 sensor A" Just wondering if anyone has any insider info here as he doesn't want to be replacing parts willy nilly. Starts and runs fine, he says it's sluggish, I wouldn't know, doesn't seem too bad to me. Inclined to think not the Crankshaft sensor given that it starts fine. I should add the CEL was intermittent until recently, more evidence that its a sensor? Possible other causes are naughty camshaft sensor or more seriously a stretched chain or bad tensioner, there is certainly a rhythmic ticking from the engine, probably unrelated, it doesn't sound like a rattling chain and my high tech screwdriverscope didnt pick anything up in that area, possibly a noisy injector. I don't have an oscilliscope to properly test the sensors or really enough time with the car to do too much as his wife needs it every day. Or something completely different one of you very smart gentlemen know about? Cars are too fancy now with all their sensors and whatnot.
