P1130 Code 2002 Toyota Camry Solara
I have a 2002 Toyota Solara 2.4L 4 cylinder.
(Currently:199k miles) Months ago I got a P0420
code meaning I had a bad catalytic converter.. The
code was reset multiple times to ensure the
catalytic converter was indeed bad. I eventually
changed the catalytic converter. After that, the
P0130 code popped up meaning I had a bad o2
sensor. That code was also reset. I changed the o2
sensor.. I soon got a P0171(System Lean etc..) &
P1130, I reset those codes and the P0171 went
away. But the P1130 came back.. I contacted the
company I ordered the o2 sensor from (thinking it
was defective) and they gladly sent me another
sensor which I currently have installed.. but the
code persisted which is leading me to believe the
problem is not the sensor but something throwing
the sensor off. The P1130 code: Air/Fuel Ratio
Sensor Circuit Range/Performance Malfunction
Bank 1 Sensor 1. Now this code is tricky because
there is no definite solution just by reading the
code. I changed my spark plugs and ran some sea
foam through the tank, no change. I bought an OBD
scanner to get some live data/freeze frames. First
off, my car cannot stay in Closed Loop. It either
shows, OL drive/CL-Fault or just simply OL. When it
is in CL, my Short Term Fuel Trims range from -20%
to +5% and my Long Term averages -10%. The
Upstream O2 sensor (B1S1) reads 3.289v in open
loop. In CL-Fault/Closed Looo: O2B1S1 ranges 3.3-
3.5 which doesn't seem ok at all. The Downstream
(O2B1S2) reads just fine averaging about 0.89v. All
other readings seem about right. The MAF averages
2.89 at idle and my sparkadv averages 15(idle).
Performance issues include: hesitation when
accelerating, loss of power, very bad starting
problems (especially cold starts), hard shifting
between gears, very bad gas mileage, a very rough
low idle (660 average) and my car smells of
gasoline.
Currently lost and looking for possible solutions. I'm
thinking I have a bad coil, a leak, bad injectors or
just a defective o2 sensor.
