P-0171 indicates an issue with the Mass AirFlow Sensor. It is probably dirty. Locate this device on the intake tube, between the Air filter and the intake manifold. Remove the wire connector. Remove the 2 phillips screws that holds it onto the air tube. Using a flashlight, examine the interior of the sensor. You will see 2 small wires. If they look "fuzzy", or if there is any debris on them, this is your problem. Using brake cleaner spray (get it at a parts store), spray the interio until the wires are super clean. Do NOT use compressed air to clean it, the air pressure will break the wires, rendering the sensor useless. Refit the sensor, and drive it for a while, the light will eventiually go out when the ECM relearns the signal from the now-clean sesnor. Hope this helps, and thanks for using FixYa. Let me know what you find inside the sensor.

SOURCE: Code P0401 1998 Toyota Camry
I'm assuming that it is a four cyl.The p0401 code is for insufficient egr flow.Most of the time it is the egr vsv valve (vsv means vacuum switching valve)which is what controls the vacuum to the egr valve to open it.It is kind of hard to get to as it is on the block under the head on the back side.If you follow the hose from the egr valve it goes to the vsv.I have also seen mice eat holes in the vacuum line which would also give you problems.I hope this help and let me know if you have anymore questions

SOURCE: code P0330
P0330 Knock Sensor 2 Circuit Malfunction (Bank 2)
Check the resistance of the knock sensor (compare it to factory specs)
The knock sensor is faulty and needs to be replaced.
Check for broken/frayed wires leading to the sensor.
There is a wiring short/fault in the knock sensor circuit

If the "evap not ready" readiness monitor never clears and you keep getting P0440,P0441,P0446 type codes, then you have a problem with the evap system. You have already tried the gas cap (good start) but there are about 6 other things it can be from electrical VSV air valves (there are 3 of them, 2 under the hood, 1 near the charcoal cannister (behind fuel tank) to 2 air operated valves on the front of the same cannister. There is also an air line that goes to one of the electric VSV valves on the air cleaner under the hood. Several oil change places have been guilty of pullling these off and not reconnecting them.

SOURCE: had the rack and pinion
while replacing a rack on any car with a airbag made into the steering column you have to make sure the steering wheel does not move while changing out the rack.......if it moves buy itself or lets just say someone was to move it for a joke and it gets out of position and after you put everything back together and turn the steering all the way the wires in the spiral cable will stretch and break...i have seen this happen all the time when you are working on the steering system....the spiral cable will turn 2.5 turns in each direction when you are installing a new one and if it is installed .5 to 1 turn out then when you drive the car and turn the wheel lock to lock the wires are going to stretch and break.....i would have to say that whoever installed the rack has caused all of your other problems and if it was the company i work for they would take care of it for you...i hope that this info was helpful and if i can help you in any other way let me know and if you would also let me and fixya know if i was of any help to you and a comment and a comment would be appreciated...thanks and good luck...have a blessed day......
