P0500 Code: Vehicle Speed Sensor 'A' Malfunction [Location] (axlewise.com)

code p 0351 refers to ignition coil A, primary/secondary---circuit malfunction====causes --wiring---ignition coil---ECM
Have that coil tested
Check harness connections for corrosion water etc

Plug wires

go have the vehicle scanned for trouble codes most auto stores offer this service for free the codes will help in assisting repair

P1391 - Not a valid obd code.
B1391 - Oil Level Switch Circuit Failure
C1391 - Not a valid obd code.
U1391 - Not a valid obd code.
Its possible you may have misread this code. If it is B1391 that would be the only code with 1391 for your vehicle.

P0351 - Ignition Coil A Primary / Secondary Circuit Malfunction. The ignition signal from the Powertrain Control Module or Electronic Control Module is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

Possible Causes:
- Open or short in the ignition coil circuit
- Ignition coil circuit shorted to ground
- Ignition coil connector
- Damaged ignition coil
- Damaged PCM

P0352 - Ignition Coil B Primary / Secondary Circuit Malfunction.
Same repair info as P0351.

P0353 - Ignition Coil C Primary / Secondary Circuit Malfunction.
Same repair info as P0351



Solutions:
- If damage, repair ignition coil circuit
- Replaced ignition coil
- Replaced PCM or ECM

P0351 Ignition Coil (A) Cyl.1 Prim./Sec. Circ Malfunction 16735 is the vehicle missing if it isnt reset code if it comes back change plugs and wires

any check engine light on? hate to say this but sounds like a ECM (brain) malfunction. but also sounds like a crank position sensor. if check engine light is on find the code and post it for more help.

The code indicates the coil pack or spark plug is malfunctioning. You can test this using an additional person. by removing the coil pack and spark plug, place the spark plug into the coil pack and ground the tang on the spark plug to the engine. Have someone start the engine and watch for a blue spark. if there is no spark, then the coil pack is malfunctioning. There is also ways to check the coil packs using a multimeter.

also, bee sure you didnt crack the ceramic part of the plug during initial installation.

p0351 is ignition coil primary circuit this USUALLY means a bad ignition coil use only a name brand coil ,but it could be a bad computer but not very common

I guess the best place to start is change plugs and wires. A timing light would come in real handy. You could check to see if you had spark on all cyllinders before you start blowing cash. If you have spark in the wires, then change plugs. If theres no spark in the wires, then the problem is before that. Like coil, or idle control sensor etc. Keep me posted and i'll try and help as much as possible. Not much a keyboard can do.
