I have a 1999 gmc 2500 van. P1345 code coming up

Changed intake gasket. Now P1345 code is coming up. Runs fine tho. Could the timing need adjusted? If the timing isn't set just right could the code P1345 come up?

I have done this before on these --- the distributer is off 1 tooth.when you pulled out the distributer some times the slot that runs the oil pump when the distributer go back in it finds the slot but it will be off 1 tooth.

One possibility is a faulty idle air control valve.
The computer controls idle speed by adjusting the air coming into the intake around the throttle.

With your code reader, clear the codes and check they stay gone.

I have a p1345 code on a 99 chevy 1500 5.7

start over! disconnect the battery. reset the dist. in properly aligned with TDC and #1 towards the front of the motor. once these steps have been taken and youre sure youre ready to fire it off, do so. make sure you set timing, you probably need to get a scanner and clear the codes. if you can afford one with "live data", it will serve you well if there are any further problems.

I changed the intake manifold on my 1997 gmc safari van that has the 4.3L engine because of a coolant leak. Now the check engine light comes on. it puts out 3 codes ( PO102 ) ( PO300 ) and ( PO507). What...

you may have broke a gasket 0n the manifold and you now have a vacuum leak explaining the high idle. also check the iac sensor it may be stock partly open or sticking

Trouble code 1345 crank sensor/camshaft sensor correlation

I had this same P1345 code on my 1998 GMC K1500 5.7 for about 2 years. Each time the code was erased, the "Service Engine Light" came right back on with the same code. I tried replacing the cam sensor, but that didn't solve it. I had the timing adjusted, it was out -13 degrees. After adjustment, the "Service Engine Light" went off, but only for a short time. Adjusting the timing is just a temporary mask on fixing the real problem and eventually you will run out of adjustment. I read about this same problem on another forum and someone recommended changing the distributor gear. So I checked the gear and a the teeth were worn. Replaced the gear ($35 part), readjusted the timing and the light has been off ever since. Apparently the gears in 96-99 are soft and wear enough to throw off the timing. This code is telling you the crank and distributor are out of sync. So before you start buying sensors and other misc. parts, try the distributor gear if you are getting a P1345 code.
