Do I have to address the issue of P1133 and p1135

[q0987]

Hello all,

My car is 97 camry LE 4l. The engine light is on today and I read the following two codes:

P1133 and P1135.

It seems that it costs lots of money to fix this problem.

Should I fix this problem at all?
If I don't fix the problem, does it damage my car in any way?

Thank you

P1133 - Air-Fuel Sensor Circuit Response Malfunction-04

P1135 - Air-Fuel Sensor Heater Circuit Response Malfunction-04

I would guess that points to your MAP or MAF (whatever you have on your system) sensor.

If you do not address this problem it will most likely kill your catalytic converter.

This is the A/F Sensor, Bank 1, Sensor 1. This will primarily affect gas mileage. You can remove this sensor and ohm the heater to confirm it is fried. Even if the heater is ok, the sensor itself could be malfunctioning. When you replace it, make sure you use a high quality part - either Toyota factory or Denso. Many times aftermarket sensors, especially Bosch, WILL NOT work in a Toyota/Lexus. Since you have a CA emission car, it will be pricey, around $150. Did you recently run out of gas? If yes, clear the codes and see if they reappear.

I went to toyota dealer yesterday. It cost $57 for checking. $499 for replacing the A/F Sensor, Bank 1, Sensor 1.

Thank you for your helps.

I'm glad you got it fixed, but holy cow, that dealer hosed you on the price, big time. If you aren't able to do repairs like this yourself, try to find a reputable indie for future problems. $57 + $499, you have got to be kidding me.

The part alone costs me $301. + %57 checking fee + xxx laber fee = 57 + 499

Americans labor is very expensive. This fee is more than my 40" LCD TV

$57 - Toyota diagnosis
$136 - Wholesale Toyota O2 sensor
$15 - O2 sensor socket
$30 - 3/8 inch drive socket set
$25 - Haynes manual (or free factory manual on this forum)
$5 - Big Mac fries and a coke

$268 - Total

This is a CA spec car and an A/F Sensor, not a regular O2 sensor so I would put in $150 for a quality Denso unit.

This is not a question of American labor rates. This is a case of an unscrupulous dealer charging you 2x what it would cost at a reputable independent shop.

Well aware of the differences but, helps to read the fine print. $136 sound better for an OEM Denso sensor?
