i am experiencing a weird issue after i have had some exhaust and header work done , suddenly when i was trying the car after the installations , the engine check light appeared along with the battery sign also illuminated in the cluster area.

the car is now not charging the battery and when i check my KPRO its giving a DTC P-0340 CMP Sensor - No signal.

the speedo meter is also not working while the RPM is ... can anyone help me here i have checked most sensors all of them neatly fixed. the alternator is also working fine , but still not charging the battery fixed and after battery is exhausted the car is now not starting due to low voltage in battery

i am getting the battery charged so i can recheck the car ... any suggestions and advice from the gurus would be appreciated , i am just in troubled waters :(

thanks in advance.

Go through the engine bay where the work was done and check for loos ewires, shorts and anything that may have been disturbed by the work.

i have done most of that , going to do it again , but if there are any heads up on which might cause all the symptoms together?

speedometer not working
battery not charging at all though alternator / dynamo is working fine got it checked also.
CMP error on KPRO error code list

Try following the Helms manual troubleshooting for the error you are getting.

i have replaced the sensor but still same error , can it be something else? what can be the causes of speedo meter not working? and also battery not being charged ?


where can i find the cmp sensors?

57-1 P0340 CMP sensor no signal


this is the exact error

Bump for help .........

checked fuse # 4 under the steering it was blown , now the CEL is gone but battery light is still there

while everything seems to be working fine , another thing i have noticed whn i hit the vtec , i get CEL and the error code came up saying

knock sensor circuit malfunction error


please help advice.

CEL gone - was a blown fuse , only problem is battery light , while battery charging etc all electronics are working fine , few things i have noticed is that my front driver window is not pulling up and down in auto mode. you have to keep on pressing the button.

also i have to disabled the knock sensor via KPRO , as whenever i use to rev up i used to get knock sensor malfunction CEL. i am assuming i have damaged the Knock sensor while diagnosing and fitting the headers.

please help ..

The window is because you have disconnected the battery. You will have to follow the window relearn procedure which is in your owner's manual.

You need to determine WHY you blew the fuse adn correct that. You obviously have a problem with the wiring in the care somewhere.

i have given multiple runs to verify i cant see anything wrong , i have my AC clip not connected thats the only thing i see missing.

rest i have O2 and knock sensor disabled because they are not working ...

the battery light is still on - can it be due to the fact my maintaince free battery is also dying? but the voltage level are NOT that bad that it should have consistent batt indicator on.

bump to bring this up !!
:twisted:

anyone - bumping for an answer !! :roll:
