Code 02-01 Ignition Signal Circuit
Code 02-01 Ignition Signal Circuit
Hey guys on saturday it pour here in MA I was driving to my house and since I have a CAI it suck up some water not much but it did and soon after that the car just die and since then it does not want to start .. it is not hydrolocking .. first the starter almost catch on fire it was smoking and hot as hell ..so I replace tghe starter but the car will not start it almost does but it doesn't and it gets flooded so I clean and dry the spark plugs and it seems to want to start but it doesn't ..the only code that came up was was 02-01 Ignition Signal Circuit .. could it be the crank sensor ??
Thanks
Thanks
Any other codes?
0201
Diagnostic Trouble Code 0201 indicates a problem with the ignition coil and power transistor. The ignition signal from the Engine Control Module is sent to and amplified by the power transistor. The power transistor turns on and off the ignition coil primary circuit. This on-off operation induces the proper high voltage in the coil secondary circuit.
The malfunction is detected when the ignition signal in the primary circuit is not entered during engine cranking or running.
The items to check include
- Harness or connectors (the ignition primary circuit is open or shorted.)
- Power transistor unit built into ignition coil
- Condenser
- Crankshaft Position Sensor (REF)
- Crankshaft Position Sensor (REF) circuit
A misfire on any individual cylinder should set a code, and a problem with the CPS should also set a code.
I would have expected to see DTC 0201 along with one of the following DTCs.
0407 - Crankshaft Position Sensor (REF)
0608 - Cylinder 1 misfire
0607 - Cylinder 2 misfire
0606 - Cylinder 3 misfire
0605 - Cylinder 4 misfire
0604 - Cylinder 5 misfire
0603 - Cylinder 6 misfire

code 02-01
Hey nmexmax , that's the only code I get . . it seems that there it wants to start but is like there is not enough spark .. can it be the crank sensor all happen when it rain and I drove thru a big water puddle ...
Thanks
Thanks
