HI , I 'm new to the forum

CAR INFO;
-1997 Civic DX Coupe US
- Manual trans.
MODS;
-Aftermarket Stearing wheel
-Aftermarket Radio


Recently the car started to turn on the CEL and ECU Lights by it self. So I connected the ODB2 scanner and it threw the folowing codes:
-P1297(Electrical load sensor circuit/voltage low) it apears some times.Alternator and battery tested and all good.
-P0135
-P1337
-P0141

So I Changed both O2 sensors and Crankshaft position sensor , reset the ECU, but the car did the same thing It turned on the CEL and SRS Lights and the sacaner threw same codes again.

Need some help asap :S !

 

Double check the ground connections from the engine to the radiator support

 

Check whether fuse 15 is blown.

the fuse #15 its good
i did take the ELD form the fusebox
Where i can find the same ELD shown in the pictures below?
ALSO:
i noticed that the ECU clicks after i put the key in on position , is that normal?

 

Did you voltage test fuse 15 as detailed at the link I posted?

 

yes,i did test the fuse #15 as the post says and all good! .At least something is looking good.

 

If you reset the ECU, do all codes return?

 

yes!

 

UPDATE:

New ELD, no more P1297, But the other three codes are still there:
-P0135
-P1337
-P0141
As i said before i have changed the crankshaft position sensor and both o2 sensor.

 

The crankshaft position sensor is inside the distributor.

The crankshaft fluctuation sensor is behind the crank pulley and lower timing belt cover.

Which are referring to?

Does battery voltage reach the heater element pins in the two O2 sensor plugs?
