After trying to install my edge comp. It threw the check engine light.. I removed the comp and cleared the light it stayed off but i was bored and ran the test for codes and it gave me

1687
0237
0238
1474
0341- Going to install the new crank sensor soon....


Like I said The truck rungs great and the check engine light hasnt come on since i removed the edge.....


Any help would be great!!

 

1687 - No Cluster Bus Message
0237 - Turbocharger Boost Pressure Sensor Low
0238 - Turbocharger Boost Pressure Sensor High
1474 - Low Fan Control Primary Circuit Malfunction

They 1474 is really throwing me off as there is no fan for the ECM to control.

Are you running a boost fooler with the Edge?

 

How can both occur?

Rich

 

Theory:

High boost code from Edge chip
Low boost code from leaving the MAP unplugged and running the engine (ive done that myself )

 

According to my source, there is no 1474 DTC for Dodge in 2001....

As near as I can tell, 1474 is an OBD II DTC for Ford.....

1474 is stated as : P1474 HCF Primary Circuit Failure (Ford)

OR

P1474 LFC Primary Circuit Failure (Ford)

I'm not saying I'm 100% correct but this is what I come up with......To my knowledge, there is no PCM control of a fan circuit that would allow a DTC to occur if there was some type of fan circuit malfunction......somebody please correct me if I'm wrong.

 

1687 is another goofy one too......JBODY are you out there?

Could this have something to do with the CANBUS connector that the Comp plugs into?

I think he could shed some light on these uusual DTC's.

 

Sorry for throwing you guys off but the code is actually 1475 not 1474... Like I said this all started after installing the edge comp

 

1475 don't make much sense (to me) either. 1475 = Aux. 5 Volt Output Too High
