I think your Mazda guy is trying to sell parts, not necessarily give you what he thinks will work best.
With the universal Bosch part, you will need to splice the sensor into your stock harness. -Bryan --- On Tue, 9/23/08, Lee Davis <[EMAIL PROTECTED]> wrote: From: Lee Davis <[EMAIL PROTECTED]> Subject: Pre cat Oxygen sensor for 2002 -- Mazda OEM or other brand? To: [email protected] Date: Tuesday, September 23, 2008, 9:08 PM Message After continuing to get the P0171, lean CEL, I took my supercharged, intercooled 2002 Miata to the local tech comm.college and the guru ran a computer program that looked at my oxygen sensor. He said it was lazy -- that it did not read fast enough (crossing the 440 line (or something like that) , up & down on the moving scale, indicating to him that it was slow reading, else the up and down lines would have been closer) and, therefore, my oxygen sensor should be replaced. I think I have determined the Mazda part # to be BP6F18861B (for pre cat) . I think that the one that is # BP6G18861C is the post cat sensor. Anyway the local Mazda parts guy said "be sure to use Mazda parts and not a cheap one like a Bosch, which may only last a week". The OEM part # BP6F18861B is $180.90 @ Trussville Mazda. The local Mazda guy said $295, installed. My generic mechanic said install is $20, for the type with the wire connector. The sensor just screws in and the wires just plug in. Some sensors require you to use the old wire connector and somehow connect the wires on the new sensor to the connector. What do you experts think? Are the after market sensors like Bosch and Walker ( # 25024128) to be avoided?
