bad VSS (chevy) k1500 not Suburan. 4th gear dead. NOT TOLD ALL 4wd or 2wd truck, and matters huge on VSS. 5.0L? no car mileage told or on tranny.. the scan tool tells you VSS is dead.,veh.speed,sensor. the transmission shifts by lots of variables and FOR SURE SPEED, is one, so the would't cause is dead wrong;. first thing to do is learn what box is there. (real name) GM car is GM transmissions sure but which exact one. and why do you ignore the speedo/tacho, they must work. chevy 1999 k1500 4L60E RPO Codes M30 4L60e electrically shifted by the TCM brain (it or PCM/TCM)_ to shift electronically many things most work VSS, and all speed sensors, and shift solenoids. and more this code smacks of cam timing errors top me. Trouble Code: P1345 (5.0L V8 VIN M Auto) Crankshaft Position (CKP)-Camshaft Position (CMP) Correlation( < this word means OUT OF TIME in geek speak) the PCM predicts next cam pulse and is way the heck off time, and tells you it is and does not lie. OMG it has an old Distributor and CMP is bad or distributor ws never timed correctly as the SM directs. SM= service manual. this error can not be ignored, but back to transmission problem in drive To shift up the TCM brain must know speed in drive upshifts fail, hard. I am reading your SM now. learning what version this 4L60 is and all sensors and if it has line pressure control solenoid. to get the VSS DTC error one must drive long time to get it. but the speedo did not lie to you , VSS is dead. yes it has PCsol PCS solenoid that sets main tranny line pressure just before the shift, ( 3 soles to shift , not 2) as you go higher gears the main line pressure needed to do so needs lots more pressure from 75PSI to 175 PSI in drive. if not gears fail. now 2 photo to prove all this. first is VSS then 2nd is PCsol.

check and test module and harness https://www.youtube.com/watch?v=i04AE6r6YLM

If I am not mistaken, these have 2 separate flashers. One for the turn signals and one for the hazards. If memory serves correctly, the turn signal flasher is square and the emergency flasher is round.

Check your crankshaft sensor, if it's bad the computer goes into fail safe mode and kills power to the fuel pump.

Sounds like the engine computer is falling into the limp in mode. The best way to know if it's the computer or a sensor is to run a diagnostic test . That way any codes stored in the computer will pinpoint the problem

I would check for a bad wheel bearing on the rear, also check the u-joints on the drive shaft.

check the fuel system pump, regulator, fuel pressure damper , return valve when the key is on the system needs to be pressurized and maintain pressure, if you dont have this , recheck your fuel system if everything is ok, than cranck the engine and look for injector fault

Which ECM / PCM fuse was burnt ? How did you check fuel pressure ? With a pressure gauge or just pushing the scrader valve an seeing fuel dribble out ? Pull a plug wire an see if there is spark . Engine Cranks But Does Not Run Description The Engine Cranks but Does Not Run diagnostic table assumes that the battery condition and the engine cranking speed are OK. If the battery condition and the cranking speed are not OK, refer to Diagnostic System Check - Engine Electrical in Engine Electrical for diagnosis. Make sure that there is adequate fuel in the fuel tanks. Diagnostic Aids • Check the duct work between the mass air flow (MAF) sensor and the throttle body for air leaks. • A malfunctioning MAF sensor may cause a no start or a stall after start. If you suspect this, disconnect the MAF sensor. The powertrain control module (PCM) will default to the speed density in order to calculate the load and the air flow. If this corrects the condition and the connections are OK, replace the MAF sensor. If the steps above check OK, refer to Symptoms . Test Description. The numbers below refer to the step numbers on the diagnostic table. It may be necessary to connect a battery charger to the battery for this step. If the battery state of charge is low, the scan tool may reset during the cranking test. This step tests the ignition relay for proper operation. The ignition relay supplies voltage to the injectors and the ignition coils. When the ignition relay is not operating properly, a no start condition occurs. If the test lamp does not illuminate, this indicates the ignition relay is not suppling a voltage to the fuses. The crankshaft position (CKP) sensor is located above the starter. The camshaft position (CMP) sensor is located at the rear of the engine behind the intake manifold. The ignition feed circuit for the CMP and CKP sensors is internally connected within the PCM. A short to ground on either circuit will cause a no start condition. The fuel cap may need to be removed in order to hear if the fuel pump is operating. At this point the engine should start. Refer to Hard Start for further diagnosis.

Check for continuity of the ground.

this code is for a faulty clutch switch, replace it near clutch pedal

short or wrong fuse

check the trailer harness if your truck came with trailer package those harnesses are known to go defective. do daytime running lights work?

Check the switch in the front end,,,,screws in the side of the pumpkin,,,the diff,,,,think its a 32mm wrench size?????remove it ,,plug it back up to factory wires, ,,,,may need to groung it to side of frontend or metal surface,,,turn key on ,,, turn 4x4 switch to 4wd,, see if it extends out about 1.5"?? or so,,,they used compressed gas heated to move in and out,,,check your wires on the transfer case to,, for good conection

Then you are looking at your power steering pump. It may be going out.

Throttle position sensor controls this i believe,,,check for code even if the check engine light is not on

I'm assuming the engine cranks over with the starter, seems to start for a second or two then dies. Does the message centre have a flashing "SECURITY" message? If so, you have a Passlock II problem. To get it running you'll have to do the 10 minute relearn procedure, or if that fails the 30 minute relearn procedure. I could post both procedures if you like. To fix it so it will never fail again you will have to: 1) bypass the sensor in the steering column, or , 2) hardwire (solder) the 3 wires to the sensor, or , 3) replace the sensor. This last option rarely works due to the problem being in the connector contacts, therefore my preferred method is either option 1 or 2. (I really wish GM would fix the contact issue by using gold flashed contacts and not crummy tin plated ones which tarnish over time)

Mortec.com u will be amazed

take the sliding pin out clean it with engine degreaser,(DO NOT USE WIRE BRUSH),if it does not work, you have frozen caliper and need new one
