So which one did you break the one in the valve cover or the one down low??

What's in the valve cover? You're the only one who keeps bringing up the valve cover. :wink:

The crank angle sensor is mounted down near the crankshaft. The connector for the crank angle sensor connects to the wiring harness near the valve cover, but the voltages and continuity checks in the diagnostic procedure checked out when I did them last night, so it's not the connector or the harness.

I know I'm just a PITA... :(

But what is the diffeence betwen your Crank Angle Sensor and the Cam Possition Sensor???

The cam position sensor finally gave in to the heat recently and caused misfire, Check Engine Light. A trip to Autozone on the way home got me a free OBDII sensor read of code P1345. The temporary fix was simple. Don’t run the air conditioner, and check miata.net. A quick search revealed others who’ve experienced this and a new cam position sensor fixed it. So I called Trussville Mazda and ordered a new cam position sensor.

When the part arrived for ~ $90 including shipping, I spent five minutes disconnecting the battery, unplugging the electrical connector from the sensor, unscrewing the 10mm bolt, pulling out the old sensor and popping in the new one, tightening up the bolt, and affixing the connector. I left the battery disconnected for about an hour while I ate dinner to make sure to wipe away any bad habits the ECU may have picked up. I reconnected the battery and haven’t had a problem since.

::Censor:: I'm an idiot. :punchout:

Somehow, in my exhausted stupor last night I decided to follow the diagnostic procedure for the crank angle sensor. Now I understand where Mick was going - rereading the P1345 page it is related to the cam angle sensor. How the heck did I get the crank angle sensor involved? :confused:

Does it help that they're both attached with one 10mm bolt and one 3-pin electrical connector? ::Clown::

Sigh... back on the phone to Mazdacomp...

See... his meddling is good for something! ;)

Watch it... You are going to make his head swell again! ::Clown::

You mean it gets bigger?

That big head kinda reminds me of this guy:

The one in the valve cover.

Actually, I'm not so sure the sensor is actually bad. However, the plastic retaining clip was broken, so the sensor leads wouldn't stay connected.

Yeah, the TCB fix would have probably involved some electrical tape and the old sensor, but another $50 at this point in the preseason is just a drop in the bucket. ::Censor::

Your rebuilder did good if that's the only sensor that is broken... Those plastic pieces tend to get very brittle after years of heat cycles.
