p1130, p1135, and p0125

[chester9ll]

My friend has a 2000 tacoma with the 3.4 v6 with almost 107,000 miles. She got the oil changed and right after my check engine light came on. She scanned the codes and got a p1130 (air fuel sensor circuit range/ performance), p1135 (air fuel sensor heater circuit response mal), and the new one that just started today a P0125 (insufficent coolent temp for closed loop fuel control). The only thing I can thing of is the O2 sensor when i look everything up. She is about 3000 miles away and doesn't really know anyone there, she just moved and started a new job. She went to the garage and they wanted to charge her a arm and a leg just to look at the truck. If anyone has had this problem or has any idea i would appreciate any help i can get thanks

P0125 could be caused by a faulty cooling system thermostat or engine coolant temperature sensor. The cooling system problem may have caused the P1130 & P1135 codes. I would work on the P0125 problem first.

You can save money by troubleshooting before throwing parts at it.

i would troubleshoot the problems but its not my tacoma it's a friend's truck and she knows nothing about her vehicles. i want to get her a start if she takes it to the shop they don't try and rip her off. thanks
