Hello,

I need some help. I have a 1997 Montero. The engine won't start and the ecm shows a 304 camshaft position sensor malfunction, bank one. I replaced the camshaft sensor and then found that the power supply from the ecm to camshaft sensor was bad, so I replaced it. The harnesses all check out: power from ecm, ground, and connection to MFI are all good.

does anyone know what the Bank One means on my trouble code?

thanks for your help.

Barry

 

bank 1 represents the cylinders on the passanger side of your car.

 

Code p0304 is not for cam malf its for cylinder 4 missfire.

 

Thanks for the help. I did transpose the numberit is 340, not 304. I've replaced the camshaft sensor and checked the harness and still I get the error code. Could something else be tripping up the camshaft sensor?

 

Could be a bad pcm if the harness and sensor are ok.
