MAKE: toyato MODEL: avalon YEAR: 2008 MILES: 89000 ENGINE: 3-5 v6 DESCRIBE ISSUE....I recently changed spark plugs for firsts time. I broke a wire on a sensor bank \ a and so I replaced with a new plug piggyback. I matched wires up to piggyback and started car up and the engine which was on went off. I drove car maybe 10 miles then again engine light came on again. I checked car with a diag checker and this message came up POOiy oyeS 1/1 generic, crankshaft position camshaft position correlation bank i sensor b. I replace the sensor and engine light goes out but when I drive car light comes on and the diag scanner states same thing. I can erase the codes on scanner and engine light goes out. I drive and again and engine light come son and again I erase and does same thing, the scanner shows the Pooiy in the read codes and pending codes but again I can erase and the scanner says cleared codes but again I can drive maybe i maybe 10 miles but engine light comes on. the car was fine until I changed spark plugs and broke one wire form a sensor but I corrected that problem. need some advice.
