Fault code 11, 21
Hi I am getting code 11, 21 and the car runs like crap. Should i check the Coil plug and harness as our cars don't have a CAS?
What voltage should the coil get?

11 is crank angle sensor. i had this pop up on my car once, i reset it and it's never been back, i dont even know what it is. 21 is ignition... my guess is its the one plugged into the coil??
Most Nissan distributor ignition systems have the Crankshaft sensor is inside the distributor, Optical LED type. Is there oil leaking through the dynamic seal covering the sensor plate? You will have to partially disassemble the distributor to find the signal/sensor plate. Make sure you recheck your timing after install.
