The TA204 coil-on-plug (COP) and signal probe from Pico Technology is the fastest way to check coil-on-plug ignition coils and spark plugs.

• Find misfires fast
• Displays scope patterns of the secondary, faster than scoping the primary
• Works on all automotive scopes capable of displaying ignition patterns
• Can also be used to investigate injectors and other inductive actuators
• Flexible design allows for easier access to hard-to-reach components
• No batteries required

Like distributors, spark plug wires are starting to disappear from cars. With the new COP ignition systems the ignition coils are connected directly to the spark plugs — eliminating the need for the spark plug wires. With no high-voltage spark wires, a COP probe is required to be able to pick up the secondary ignition waveform.

As standard the TA204 COP probe is supplied as a kit (PP357) complete with the TA033 BNC to BNC cable in order to connect to your automotive scope.
