Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Can you give me the actual "p-code" that was retrieved that led you to replace an O2 sensor?
ok- here's the problem. P0135 is a problem in the Internal Heater for the A/F Sensor (aka Oxygen Sensor) for Bank1 Sensor1. The PCM uses this internal heater to get the sensor to normal operating temps within a matter of seconds on cold starts. This sensor is located mounted to the exhaust manifold closest to the firewall. Long story short- the wrong sensor was replaced.
Then, what is the number for the correct sensor and where is it located?
And if this is the wrong sensor, why did that number show up on the meter?
The diagram does not look like my engine. I have a 1998 Camry with a
V6 3000 Four Cam 24. The mechanic says he thinks it has only 2 O2 sensors.
Since the car has always been in New York, I assume it has Federal emission.
The car has Federal emissions, it says "not for use in California." Please send the correct part number. Also the number for B2, S1 which, I assume is the one that was replaced incorrectly.
This is actually the second time they've replaced the O2 sensor with no results.
I sure hope it works this time.
Well, when you have a P0135, and replace the wrong sensor, unfortunately, you will not see results. Had the correct sensor been replaced the first time, you would have been past this a long time ago. With all due respect- if your mechanic doesn't know where "Bank 1" is on a V6 Toyota, or that a P0135 is a code for Bank1 Sensor1, or doesn't "know" there's more than 2 Oxygen Sensors on a V6 engine - it may be time to find a new mechanic. He's going to cost you a TON of money in the future with mis-diagnosed problems, and replacing parts at random. Like I say- this is an extremely common fail item, and there's no reason the correct diagnosis and repair shouldn't have been made the first time.
As for the part#- I onyl have access to Toyota OEM Part #'s, however, if you take the OEM part number to any local "aftermarktet" parts store, they can "cross over" the OEM to whatever aftermarket brand they sell (I would recommend a "better quality" parts store, like say, NAPA as opposed to AutoZone-you get what you pay for!). You can also order the part by name "Bank1 Sensor1 without Cali emissions" and you'll get the correct part. On the Federal model, the part for Bank1 and 2 are the same.
