Hi guys , does anibody have a P0017 code with the installation of Bates valves springs , and does this code make a SS difficult to start ?

Don't know if this will help ya or not but here's GM's description of the P0017 code.

DTC Descriptor
DTC P0017: Crankshaft Position (CKP) - Exhaust Camshaft Position (CMP) Correlation


Circuit/System Description
The powertrain control module (PCM) uses the crankshaft position (CKP) sensor and the camshaft position (CMP) sensor information to monitor the correlation between the crankshaft and camshaft positions.

Conditions for Running the DTC
• DTCs P0335, P0336, P0340, P0341 are not set.

• The engine is cranking or running.

• DTC P0017 runs continuously when the above conditions are met.

Conditions for Setting the DTC
The PCM detects that the timing between the crankshaft and the camshaft is incorrect.

Action Taken When the DTC Sets
The control module stores the DTC information into memory when the diagnostic runs and fails.
The malfunction indicator lamp (MIL) will not illuminate.
The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Failure Records.
The driver information center, if equipped, may display a message.
Conditions for Clearing the DTC
A current DTC Last Test Failed clears when the diagnostic runs and passes.
A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other non-emission related diagnostic.
Clear the DTC with a scan tool.
Diagnostic Aids
• Inspect the engine for any recent mechanical repairs. An incorrectly installed camshaft position sensor, crankshaft, camshaft, or timing chain can cause this DTC to set.

• An incorrectly built exhaust camshaft can cause this DTC to set.

you might make sure you didnt like pinch a wire or leave the crank sensor unplugged. if thats ok youll probably need to make sure all the color links on the timing chains are lined up on the cam gears and crank gear.

i just re read that description. you need tomake sure the chains are lined up right.

it's not the Bates springs that gave you that code, did you install Cam's.

I had cams installed with my stock springs, and I got that code. you have to use HP tuners to get rid of it.

beware of the Bates Valve Springs.
I broke 4 causing me to bend a valve.
I switched to the Ferreas and no issues.
my stock were better then the Bates dual coil spring. I ran a year with stock and no issues. 5 months with the bates and I was fu*ked

It sounds like you didn't install the cam with the correct timing. You must be off by a tooth on the gear, or you didn't install the position sensor correctly.

And Bates single coil springs are bad news, I must agree. I too had an engine destroyed by them. Ferrea dual coils all the way.

player_1

actually I had the Bates dual coil installed. but it was always the outside spring that broke.
as for the cams if you where to install these cams off by one tooth the valve would bottom out into the cylinder.

I have the same problem HP tuners cleared the issue.

So true! and this is what happened to me the first time around

I need help with this too. My engine is back together and started fine....well actually after the 3rd crank. Idled fine but i threw the P0017 code. When I was assembling the engine I checke the timing 3 times.....every time was perfect!! While the engine was started there were no wierd sounds. My coolant hoses got hard and engine got a little hot....I have some Dexcool but I only used H2O for now.


BTW all mods in garage (I didn't put in the cams in yet)

Update..............

I just unplugged the cam sensor and I still get the P0017 as well as a couple others.....Not sure what else I could check.....input?

WSFrazier

You Cam sensor might be off. Hopefully you didn't just plug it in and hope it works. It needs to be aligned correctly.

Another cause is if the timing is off on the chain. A bad timing chain tensionor will also cause this if there is a lot of slack in the chain.

M88ArRamadi

I did everything by the book. i checked my timeing like 3 times. All times were right on. The cam sensor was good too....by the book. I unpluged it and still get P0017....WTF?

WSFrazier

Well unplugging the cam sensor won't make the code go away, lol.

I believe when we went by the 300HP LSJ Build Book, they were actually aligning the Cam sensor incorrectly. Can't remember. I don't run the exhaust cam sensor on my car, just have the CEL disabled in HPT.

g5mike

yes it has to be aligned incorrectly to get the best timing

M88ArRamadi

what???

I hate aligning that stupid sensor!!!! Also if I disable it wouldn't it be hard to start??

WSFrazier

It takes about 10 cranks to start. But it will indeed start, lol. The expression on people's faces is priceless though.

I should have a new metripack for my sensor soon to get her back to normal.

M88ArRamadi

I can't leav it like this.......I think I'm going to fix it later.....Damn that pisses me off

M88ArRamadi

Air ratchet FTMFW!!!!! it was the position of the cam sensor....God damn book was wrong. I'm not throwing any codes now!!!!

Anybody have the instructions on how to install this thing the right way??

g5mike

those sensor is screwy,how much off was it??

M88ArRamadi

I have no idea......I was adjusting one notch at a time......one of the times I went to adjust it it spun almost in a complete circle. Well that was the side that i needed

WSFrazier

I think you aim the slot with the notch, when #4 is at TDC Compression stroke.

g5mike

when my cams were done i think it was moved a whole notch,**** got me though

player_1

that's right, that is were your supossed to set it
