Greetings FixKick and affectionados...
Such a great site for good info and conversation....
I'm Stumped here.
Just put an ATK rebuilt J23 long block from a 04-07 Suzuki Aerio, in my '97 Sidekick Sport 4 speed automatic. Included new CMP and CKP sensors, and am using the J23 fuel rail and cleaned/tested J23 injectors from a PickUrPart Aerio. I visually replicated the positioning of the original CMP upon assembly.
Started right up with no codes, and allowed me to get it up to temperature. I shorted the service connector, bumped the timing to 5 deg, and cycled it through restarts and exercised it up and down from idle. Idled smoothly, with good throttle response. After about 4-5 minutes, i noticed it started a shallow vibration at idle that would go away ~1200 RPM. Shutting it down, I noticed the CEL on. Reread the codes to see a P0335 Crankshaft Position Sensor code. Erased the code. Restarted the engine and the code reappears in less than 1 second.
Here's what I've done so far to troubleshoot:
1. Disconnected CKP connector. Wire loom connections are solid and continuous from CPK plug to disconnected computer connector pins. Back-probed ground wire is solid at sensor connector. No shorts. Resistance of unplugged sensor coil ~560 ohms, both at sensor and at computer connector.
2. Repeated 5 times over several days:
Upon cold start, it starts right up, fast idles nicely, comes off fast idle normally. NO CODES. After 3-4 minutes, when it reaches temperatures between 150-165F, it throws the code. Shut it off, clear the code, restart, code shows in ~1 second. Repeatedly. Each cold start, there is no code. If I shut off and restart before reaching that temperature range, no code shown, no shallow vibration... . Repeatedly.
Without a scope to watch the waveforms, I'm stuck, and may end up having taking it to a trusted garage for further probing, unless someone here has any experiences with like-kind issues.
Any ideas?
Maybe recommendations for a good two channel automotive ocilloscope for my tool chest?
Thanks
