Hi, I noticed my S2000 recently having a slight hesitation at the Hi RPM's(in vtec) I have a Haltech Pro Plug in - plugged my laptop in and it give me DTC P0373.
--Timing Reference High Resolution Signal A Intermittent/erratic Pulses

Any of you guys had this issue before or possible know where this sensor os located?

 

Hmm. I found this thread via google. I have Haltech and have the same issue. Randomly at full load between 6k and redline the engine stutters. Only once I got the 373 code. Tonight I am going to try to lower the trigger voltage threshold and see if it helps at all.

 

I found this through Google as well. Did either of you guys solve the problem? If so, what was it? I am having the same issue. P0373 isn't in my Honda Service Manual.

 

Hey guys, I was messing around with the 2-step tonight on my Haltech. The car started to run on 3 cylinders so I thought I simply fouled a plug. Drove around a bit while getting on boost thinking a little heat will clear them off...still was stumbling at idle. Car then threw the P0373 code. Lowered the trigger RPM filter but that didn't help too much. Checked the plugs and none of them looked fouled.

Any thoughts or suggestions would be greatly appreciated!

 

Hi guys,

my elite 1500 is throwing the same code, revs until 7k -7,5k and then cuts fuel, showing error 4: home signal error count.

any help please?

 

I'm having the same issue on my elite 1000. It won't even start because of this code but runs just fine on my AEM V1.
