Engine check light on my 1998 toyota camry v6 xle comes on .scanner code read p0171

P0420 indicates you have a catalyst efficiency issue; replacement of the Air-Fuel Sensor should take care of that;
The P0441, P0446 and (I assume P0440); you said 446 twice, indicates a faulty or loose fuel cap; it is not sealing properly.
Please feel free to respond to me if you have any further questions.
A FixYa rating from you regarding my assistance would be greatly appreciated.

Hi.. On your question the definition of the codes are:
P0171, System to lean ( Fuel trim)
P1130, Air / Fuel sensor circuit range ? performance malfuntion This code is exclusive california Emissions). Oxigen sensor Performance malfuntion.
The first step you need to do is Check the Oxigen ( O2 sensor)
Connections The front and the rear one.
Check the condition of the Air filter Replace if need.
Check Spark plug Replace if need.
Check Fuel condition, Replace fuel filter if need.
And Clear the Codes if averything is good.
If the code P1130 return Replace the Air fuel ratio sensor..

Ok.. I hope this help on your question. If need more info letme know.
