Description: Engine not cranked since last reset or no ignition reference signal detected during cranking
Power loss light: Off
Limp-in mode: None
Engine hasn't been cranked since last reset - Power was removed from the logic module (disconnected or dead battery, etc.) and the logic module has no memory of seeing a signal from the ignition reference sensor. Crank the engine and check for the code again. If the logic module saw a signal, the code will be cleared. This code will not show up if the sensor simply fails. The logic module must be reset and the engine cranked to see if the sensor is working.
Bad connection or wiring - Check the wiring and connections between the hall effect sensor (located underneath the distributer cap) and the logic module. Check the continuity of the two 3 conductor cables coming out of the sensor--these are prone to fatiguing and breaking inside the insulation where they exit the sensor if the cables are not properly tied down. You may be able to resolder them. Clean and regrease any corroded connectors with dielectric grease and repair any shorts. This code will not show up if the sensor simply fails. The logic module must be reset and the engine cranked to see if the sensor is working (see above).
Hall effect sensor failure- Check the ignition reference sensor and fuel injector sync sensor cables. They are the two, flat 3 conductor cables coming out of the sensor at the base of the distributer cap. These often fatigue where they exit from the sensor. Upon replacing the sensor, make sure the cables are clipped or tied to the distributor cap shroud (or elsewhere) so they do not swing around. This code will not show up if the sensor simply fails. The logic module must be reset and the engine cranked to see if the sensor is working (see above).
- Computer has been reset
- No signal from the ignition reference sensor has been detected
Fault code 11 is stored and the engine will not start (even if the ignition reference sensor is working). A running engine will stall, but no code will be stored. The logic module must be reset and the engine cranked to see if the sensor is working.
