98 Camry 2.2/P0171 System too Lean(Bank 1)
Hi all,
this code has come up (randomly) 3 times now within a month. 1 time it had 2, PO171 codes. Each time I went to Advance, and checked/cleared the code with their scanner. No change of operation noted, except 1 time when it threw the code; I noticed the idle going up and down EVER so *slightly* (not much variation at all, but enough to see the tach going up and down a tiny amount). No drive-ability issues at all seemingly for each time it threw the code(s) though!! Car has 170k on it. The car runs fine otherwise, runs smooth, idles fine/smooth. I seem to be coming up with people saying the MAF sensor could be dirty/need a clean OR an O2 sensor. BUT, the 6 cyl has a MAF sensor- I'm reading the 2.2l does not have a MAF- and to check on the MAP sensor??! I've also read the rest of the recommends- fuel filter, pcv valve, egr (clean/replace) valve, etc... I've also read, that a couple people just put in fresh plugs; and their P0171 code issue went away!!!!!! I was going to order a new O2 sensor (actually air/fuel ratio monitor) anyway, just because I recently bought the car; and wanted to get it replaced (hopefully picking up any MPG I can) because I can't say the last time it was replaced. Thanks in advance people!!!!!!!!!!!! Sincerely, Bob Z. :) |
What is the current MPG?
Issues that can cause the code: Intake air and exhaust leaks Fuel pressure/injector plugged O2-A/F sensor MAP sensor Coolant sensor for computer Change the 02 sensors and determine what happens. |

Hey again Joey...
thanks again for responding!!! I cant say exactly what the mileage is for sure (haven't really been tracking this tankful). However, I'm going on 110 miles; per the quarter tank its used since filling. And I think my tank is a 18.5 gallon capacity?!! Sincerely, Bob Z. :) |
Hello again folks,
just an update for me... I just replaced my A/F ratio sensor (finally) on my 1998 Camry 2.2l. (as Toyomoho had suggested). Cleared the code that kept popping up randomly- P0171 System too Lean(Bank 1)(Sensor 1) All seems to be fine now- no more light...... THANX Toyomoho!!!!!! Will report on mileage soon............!! Sincerely, Bob Z. :) |
Great.

I have that code on my 99 v-6 does it have a A/F ratio sensor? and where is it?
|
o2 sensor(s)
|
Hi,
its located way up on the exhaust manifold, near where the manifold meets the engine (almost). The A/F sensor is a bit more sophisticated than a regular o2 sensor I'm to understand. Price out yourself a "direct fit" A/F sensor, put a little anti-seize on the sensors threads before installing; clear your codes out after- and you should be good to go!! Sincerely, Bob Z. :) |
Average lifespan?
Whats the average lifespan of a Toyota Camry ????
My son in law just lost the 4 cyl. engine in his 99 camry 195xxx and my daughter has a v6 1999 Camry with approx. 130xxx |
Generally, take care of it and I have heard of Camry's going to 300K. Just maintain it and know the trouble spots for your make and model. What exactly happened to the '99? Did it seize, throw a rod, over heat, etc.?
