Thread: vvl check codes

I'm getting :
ingnition signal
cam angle sensor

I recently lost some whp and I'm looking for solutions .. scanner reads timing like we have it set, so there seems to be no retarding.

which ecu? B13?

yup b13.. dyno graph is a litle "spikey" after 7.5k changed wires, coil, ignition head ,rotor, and spark plugs

The cam sensor is the dizzy, weak ignition signal is from the transistor to the ecu wire. I think it's the white wire. The FSM tells you how to test it, it's a just a continuity test from the ecu harness side to the plug.
