SES light = PITA
 

P0161 O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2)
P0170 Fuel Trim Malfunction (Bank 1)
P0343 Camshaft Position Sensor Circuit High Input

Most likely O2 sensor...i'll check the MAF and possible vacuum leaks ...

Also need new spark plugs :)

I'll follow up after fixing it :)

took me long enough...cleared all except an o2 sensor ... I tried to heat it up to try to get it off I could not...tried the dealer they couldn't either...

Service adviser suggested a shop where they would drill another hole...or just try to find another cat...

To make matters worse my tranny is about to go...1st and 2nd gears are acting up ...
