Started getting p1345 on 1999 suburban with 5.7 Vortec. Measured CMP Offset was at -5.9. Dropped in new distributer and CMP Offsett went to -0.1 and no more p1345. Original distributer with 190k miles and comparing the gear with the new one it was worn alright. Appreciate the video.

You know that's all well and good, but we replaced the distributor, which will be the second distributor in three years, and I still get a code period changed out the crankshaft sensor, still got a code, changed out the new distributor still got a code. I should point out that before I brought this to the mechanic the truck was running absolutely perfectly, and all I had was a 1345 code. Since I was getting ready to take a long trip, I wanted him to look at that code, and he changed out the crank sensor, which made the truck run worse with misfiring and hesitation particularly at highway speeds. So he replaced the distributor and still got codes. At the moment, I'm waiting him for to put the old distributor back in and see if we can get it running like it was before. Other than that, I suppose it could be a bad timing chain. This is a 99 suburban base model 5.7 with 168,000 original miles. we are both at a loss as to what could be causing these codes even though the truck runs well, or at least did before he started messing with it. Any advice?

Figure it out?
@johnny04543 жыл бұрын
The ignition timing correlation needs to be adjusted by using a scan tool and rotating the distributor housing (because the camshaft sensor is in the distributor) to set the cam position sensor/crank position sensor correlation to 0°. Similar to setting the timing on an older carburated engine, but in this case, you must have an actual scan tool (not just a code reader) instead of a timing light.

My gear broke off in the engine and proceeded to coast to the side of the road, just took a chance that it was the distributor and pulled it out very slowly only to discover it was missing the gear, proceeded to call a friend and have him purchase a new distributor and a flex magnet used to fish out the washer then the gear it self, mind you this was done on the side of the road, then installed the new distributor clamped it down and turned the key" no start" unclamped it and pulled it up and did a180 degree turn dropped it back down and clamped it up, started in 2 seconds and drove off purring like a kitten and never had a check engine light on, Yes Vortech 350.

Fallowed through and replaced the Distributor starting out at TDC, had the chain and gears replaced. Ran great for 1k miles then back to the BS. I noticed this time the Harmonic Balancer had a piece of rubber missing so I replaced it. And 5k miles later still running like a 454 should.

Recently sorted a similar problem with a Jeep Wrangler. Same component but slightly different failure. At 2000 RPM and above cam signal was totally dropping out on pico. On examination the upper bearing in the distributor shaft was worn and the centrifugal force was causing the trigger shield to bump the hall sensor. New shaft sorted this. I was using MAXIDAS ds708 for live data which gave a useful PID for cam and crank sensor counts, it also showed the loss of sensor counts at 2000RPM.

Maybe an extreme scenario, but could you also be off by a tooth where the distributor gear meshes with the cam gear to set the P1345 code? It looks like there are 14 teeth on the distributor gear, so off by one tooth would be around 25deg on the distributor shaft.

If the disy is out a tooth and going either way is to retarded or to advanced and say half a tooth would fix it you could always remove the disy drive gear and turn it 180 degrees and refit roll pin you will have half the tooth that you need.

@@timquigg6835 this would only be necessary if the distributor housing doesn't have the clearance to rotate far enough to accomplish the correct timing, otherwise you simply rotate the distributor housing.

On a 98' K3500 5.7cid I will dropping a crate engine soon. My question is do I have to disconnect a wire and set engine up let's say 6° advance (just threw that number in) than connect a wire back in and run over 45 mph for a few miles as I have done on old chevys before? I have zero problems dropping and clocking my distributor. I did same years back dropped a 6L crate engine on a 2003' K2500 but don't recall how what procedure I did on it been so long.
@johnny04543 жыл бұрын
No, on these vortecs the ignition timing is controlled by the computer. The distributor housing must be in an exact location where the cam sensor signal and crank position sensor signal are exactly correlated to each other at 0° You need a scan tool to see that data.

That's a little excessive. You can buy a shim kit for these to adjust the shaft end play. If memory serves me correctly, I believe the spec is less than .050" but I'm not positive, you'll have to do the research to make sure, but there are other videos explaining distributor shaft end play on small block chevys.

@johnny04543 жыл бұрын
The distributor is driven by the camshaft, so the position of the distributor is directly correlated to the position of the camshaft. The computer relies on a cam position sensor inside the distributor to tell it where the camshaft is (by inferring the information from the position of the distributor) in relation to the information it receives from the crankshaft position sensor.
