PO335 code 2000 DTS
I am still getting a stall condition at idle w/engine at oprerating temp. Still receving code P0335. crank sensor A voltage. Install new crank sensors and had synced to PCM. Still no help. I had tech put on computer scan and no problems noted. Voltages all ok and everthing in perimeters. COuld it be the Ignition module on the Front bank of cyls? I cannot seem to get this problem fixed. It is an itermittent problem and just stalls the car with the same code over and over. can anyone help me?
Thanks,
Leon

RE: PO335 code 2000 DTS
Those cranks sensors have been through a couple updates over the years.
Do you know the colors of the last ones that were installed?
Also a poor connetion in the terminal at either end of the wire will set this code(pcm side or CS side)
I've seen them in both spots. A bad pcm is also a possability.
99 times out of 100 its the sensor itself.
If you replaced them with the most up to date ones and the code returned right away then the connections need to be carefully checked.

If the vehicle has any of the crank sensor codes P0335, P0336, P0385, or P0386 set, then the following should be done:
• Inspect both of the crank sensor terminals for signs of poor connection or corrosion of both crank sensors. Pin drag test all four terminals.
• Inspect the crank sensor circuit wires for signs of damage.
• Inspect the crank sensor circuits at the PCM for poor connections. The crank sensor terminals should also be drag tested.
• Remove the crank sensors and check for any debris on the sensor.
• Verify crank sensor location (A on the bottom and B on the top) and verify that the sensor circuit wires are in the correct cavities.
• Inspect the date code on the sensor. If it is before 0276, replace the crank shaft sensor and perform case learn.
• If the date code is past 0276, verify the PCM grounds. A voltage drop test should be less than 20 mV.
• If the PCM ground circuit verification is acceptable, then follow published PCM diagnostics.
• Inspect both of the crank sensor terminals for signs of poor connection or corrosion of both crank sensors. Pin drag test all four terminals.
• Inspect the crank sensor circuit wires for signs of damage.

RE: PO335 code 2000 DTS
Thankyou very much for your support!!. The date codes where after 0276 and I believe the sensor color was grey. The new sensors had a metal bushing on the hold down clamp area. Other than part numbers how can you tell the difference between the A and B sensor.They were AC Delco Oem's. Maybe I should recrimp both terminals on the sensor harness. I looked at the ground lug on the block and do not see any corrosion. I removed the Ignition module and do not see any arching etc. What is a drag test? I have not checked the Pcm connection harness yet. Where can I get a wire diagram of the complete sensor circuit all the way to the PCM with terminal locations, numbers? 2000 DTS. WIll ALLdata have it?
Thanks,

RE: PO335 code 2000 DTS
I always remember the black one goes on the bottom.
PCM connector C1(blue) pin 2 = ckp A signal LT Blue/White
" C2(clear)pin 65 = ckp A Ign feed LT Grn
" C2 " pin 66 = ckp A grnd Yell/Blk
The Ign module should not set this code
335 is PCM and crank sensor dig ICM has its own codes.

A pin drag test is a to make sure the female side of a connecter isn't spread open to far.
The pin must be the excact size of the male then inserted and pulled out of the female as to "feel" the amount of drag from the connection.[8D]

Thankyou for your time!! I will take everything into consideration you said. First will make sure we have the correct sensor in the right place. I beleive the wiring harnesses are correct at the sensor according to the colors of wire as you said and will confirm. then will check PCM ground and Connections. Can the PCM box be opened and solder joints checked at those terminals for the ckp's?
Thanks,

Have 2001 dhs with "po335b crank shaft position sensor a circuit performance" in the code history, but no fault light.The car just dies.It will restart and run fine for days or weeks then dies again.No fault light comes on.Is the sensor causing the problem? Thanks, Stinger
