Got an odball combination of code
My SES light came on and got codes 13, 21, & 44. So with code 44 I am apparently running lean which could be from the code 21 TPS sensor and code 13 I am guessing was tripped by codes 21 & 44. Anyone else get these same codes at the same time before?

Can't say I've gotten that combo nor do I recall hearing anyone who has, but lean O2 is almost always caused by a weak O2 sensor.
Check what your TPS voltage is doing.

Re: Got an odball combination of code
Yea, been reading on here about the voltage issue. Going to buy a volt meter this weekend to check. As far as the O2 sensor, it's not even a year old Walker unit. I may have to go back to the stock type.
