DTO p0219, p0373 on RB20

Postby KevinA » Thu Jun 03, 2021 5:43 am

I have a RB20 that has been sitting for many years. After doing some fuel system fixes,
After trying to start itm my ecu is throwing P0219 and P0373 errors. P0373 points to a bad CAS, but i can't find any information on P0219 errors.

How do I start troubleshooting these errors?

DTC P0219 Engine Overspeed Condition
DTC P0373 Timing Reference High Resolution Signal A Intermittent/Erratic Pulses

Since RBs combine the crank (engine speed) and cam (engine position) into the CAS,
could be both are related to a bad CAS sensor...

Check power to ground on the plug.
Signal should be checked with a oscilloscope.
Continuity of and between the wires and to the chassis, :arrow: disconnect Baterie, ECU and CAS for this test! :!:
