Toyota Repair: Trouble codes, mass air flow sensor, crankshaft position sensor

Question
I have a 1994 Camry with the v6 engine. The car started to run poorly and the check engine came on. I have retrieved two trouble codes: PO171 & PO335. What are these codes and what car components could be at fault? Thank you in advance.

Answer
The 171 is a lean code. Youll need a MAF Mass air flow sensor. Its in the intake tube housing.Thats also why it runs poorly.
The 0335 is crankshaft position sensor.
Its a sensor at the front of the engine by the crankshaft pulley.
Youll need to replace that as well.
I havent seen those two codes together often.
They may not be related but in fact two seperate failures.
