My 2010 Prius III been giving me problems. I am having the engine code P2273 and 0038. The dealer said replace both o2 sensor and it will solve the problem. They tried to charge me for $1000 dollars for replacing both sensors. I replaced them on my own, but the codes are still there. Please advise. My car has 187,000 Miles on it.
Hello did you find any solution to your problem ? My Mechanic said changing the engine module relay will possibly solv the problem ?
hi .i got a prius 2010 when i drive some km there is like air suction in the engine and the gear start to fail and the triangle light on and engine light too and then i continue to drive with engine light on works perfectly, the ob2 scanner say battery fail,is it the e.c.u and inverter,.. I REACH 143000KM
This will be hard to fix without logging some data. I would like to see how the short/long term trims, MAF, air fuel sensor and rear o2 sensor behave under a variety of conditions. I suspect the issue has something to do with the MAF acting differently than what it is reporting and is causing the car to be over-fueled.
