Q: My question is regarding the check engine light. on 2001 Toyota Solara

Auto Zone pulled the codes and it read knocks sensor. The cat at Auto Zone asked if the oil change was overdue? I told him yes, it was approximately 2k overdue. He said that frequently, changing the oil will fix the engine light staying on. As I drove about 1/8 mile away the check engine light came back on. Is this telling me that the knock sensor indeed needs to be replaced? Thank you,

Yeah, in retrospect that was a pretty dumb question. Thank you for your resonse. After talking to a friend who is an ASE Master Technician, he advised me that there are two knock sensors located under the intake manifold. He said that Mitchell called for like 3 book hours. The cheapest replacement parts I have found are about $95. each. I've been laid off from work and have until the 31st to pass emmissions inorder to buy a $20 tag. I am just searching for an alternate solution. Any Ideas? Or am I going to have to sell enough blood to rectify this deal? Thanks again for your time and expertise...
