Usually, the engine and chassis number of nissan car can be seen in engine bay. Like a credit card size and all info of the car are casted on the shiny metal. Location in engine bay usually placed on a clear portion of a chassis. Sometimes it is located at driver side wall when you open the door. Other are located under the front passenger seat.
Toyota C1100 Possible Solution :
The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver
Flashing
D4 light is an error from the TCU (transmission control unit), so you
got something going on with your transmission. If you want to pull the
error code, remove the passengers side kick panel and look for a pair of
wires with a blue connector at the end. Stick a paper clip or some
other piece of wire into each hole of the connector to short the wires.
Put your key in the ignition and turn 2 clicks. The D4 light will
flash the code...short flashes=1 and long flashes=10. Add the number of
short and long flashes to get your code. Errors are below:
0-Transmission control unit (TCU) faulty. 1-Lock-up solenoid 'A' circuit open or shorted. 2-Lock-up solenoid 'B' circuit open or shorted. 3-Throttle Position Sensor circuit open or shorted. 4-Vehicle Speed Sensor open or shorted - No signal from speedometer. 5-Shift Lever Position Switch circuit shorted. 6-Shift Lever Position Switch circuit open. 7-Shift Solenoid 'A' circuit open or shorted. 8-Shift Solenoid 'B' circuit open or shorted. 9-Counter shaft or transmission speed pulse generator open or shorted. 10-Coolant Temperature Sensor open or shorted. 11-Engine RPM (Ignition coil signal) open or shorted. 12-(No code 12 used) 13-Main shaft speed pulse generator open or shorted. 14-Linear (line pressure control) solenoid open or shorted. 15-Kick down switch circuit shorted.
Had this happen to my '05 Vibe (Matrix evil clone) recently. Mechanic read & reset codes. The non-flashing Engine light showed 2 large emission leaks. The VSC could be any number of things. He said hopefully it was a false positive on the VSC... potentially expensive to fix. Lights stayed off for a couple weeks & are now back on. I'm planning on seeing him later today. Also, said stability light stayed off, it is still working. fwiw...
Good Day qits81, if your vehicle does not do anything funny while running it is nothing to worry about. Under normal operating conditions the engine control unit runs an automatic system diagnosis program to ensure that the engine runs at an optimum. As soon as the engine control unit received "feedback" from the sensors and all is o.k the light switches off. If there is a problem with one or more of the systems the check engine light will stay on to warn the operator that they need to have it checked out.
