2006 Lexus ES330 Q&A

2006 Lexus ES330 Question: Engine light on (solid, yellow)Errors: P0422 EES small leak/P0305 cyl. 5 misfire

Came on first drive after rear-end collision repair. mileage=62K; vehicle checked every 3mos. Shop says unrelated to collision, $943 estimate to fix! Insurance says not related. Awful coincidence or something more? -
Answer 1
It would help to know what the shop is saying is wrong before can offer opinion. -
Comment 1
Shop said it's an O2 sensor located in the front of the vehicle and therefore not triggered by rear-end impact. But I also read that the codes are often misdiagnosed. And if, in fact, it is an O2 sensor, the estimate given is double the high average for repair. Thus, I've lost confidence in the shop. -
