Reading a CKP waveform — find TDC the scope way
How the 60-2 missing-tooth gap pins TDC, and what damaged teeth, wiring faults and air-gap problems look like on the trace.

How-to.
From the bench.
Short, practical walkthroughs from the people who use this gear every day — how to capture each signal, read the trace, and turn a waveform into a diagnosis.
Lazy lambda vs a healthy switch
Side-by-side narrow-band O₂ traces — brisk rich/lean switching against a slow, biased sensor that fails emissions.
COP ignition kV — firing line & burn time
Read the firing line and burn line on a coil-on-plug capture to separate a lean cylinder from a fouled plug.
In-cylinder pressure with the PDS500x
Put a transducer in the bore and read compression, valve events and exhaust restriction a static test will miss.
Injector solenoid pulse & inductive kickback
The kickback spike is your health check — here's how to read pintle bumps, weak coils and driver faults.
