Error Code P3100: What It Means & What To Do?

<<See All OBD Codes

The OBD-II Code High Voltage System that might not perform is means of a Manufacturer Regulated DTC.

Whenever the Hybrid Powertrain Control Module suddenly fails at a self-inspection, this will set code P3100.

What causes this problem with the Manufacturer Controlled DTC?

Generic results of P3100 comes with shorted, open, corroded, or damaged wiring circuits or connectors, defective shift solenoid(s), faulty engine drivability sensors (even the engine temperature sensor), dirty or polluted transmission fluid that limits flow, faulty valve body, a defective PCM. Though a PCM failure is uncommon.

1. Powertrain Control Module - Abnormal engine behavior might specify a faulty or 
   failed PCM. A failed computer might result in a vehicle that stalls unpredictably or fails to start at all. If the PCM is experiencing any issues, it might withstand the timing and fuel states of the engine that place a negative affect on the vehicle as it processes. A faulty PCM may cause a vehicle that experiences a reduction in fuel efficiency, power, and acceleration. A faulty PCM might be dealing with a vehicle that fails to start or struggles to restart. If the PCM fails entirely, the vehicle remains dealing with a loss of engine power control, so it might fail at starting or constrict with trying to run as an outcome. The engine could still be cranking, but be given no critical inputs by the computer, so it will withstand to start entirely.
2. Crankshaft Position Sensor - The most generic symptom related to a defective or failing crankshaft position sensor is complications starting the vehicle. The crankshaft position sensor inspects the position and speed of the crankshaft, also other parameters that engage into the task when engine is starting. If the crankshaft position sensor is dealing with a problem, the vehicle may have irregular starting troubleshoots or not be starting at all. Another symptom generically related to a afflicted crankshaft position sensor is irregular stalling. If the crankshaft position sensor or its wiring are faced with any problems, it can result in the crankshaft signal to disconnect as the engine is running, which can lead to a stalling engine. This typically signifies a wiring issue. Whatsoever, a bad crankshaft position sensor can create this symptom as well. With inconsistent input that comes from the crankshaft position sensor, the engine control unit isn’t able to make the repairs to spark timing and fuel injection as the engine speed rises. Slow or unbalanced acceleration can lead to a loss of consistency and make it challenging to sustain an ongoing speed. If you can feel or hear a stutter sound in the engine, it might signify cylinder misfires coming from a defective crankshaft position sensor. A failing crankshaft position sensor can’t provide the correct data about positioning a piston in the engine, resulting in a misfired cylinder. This might also happen because of a defective spark plug timing, but if the spark plug is checked out, then the crankshaft sensor is the most distinguished source. Another sign of a crankshaft position sensor problem is a rough idle. During idling at a red light or else coming to a stop, you might see the engine grind or vibrate. As this takes place, it defines when the sensor is not inspecting the crankshaft’s position, causing vibrations that are affecting all-inclusive engine power. The shaking can also impede with the engine’s mileage tracking. Any vibrations that are not so common have to be monitored by a mechanic right away. Missing consistent timing data by the crankshaft position sensor, fuel injectors will not pump gas into the engine successfully. The engine will consume more fuel than it needs during short and long drives, decreasing utmost fuel economy. Make sure a mechanic tests the sensor, as inadequate fuel economy can take place by other problems too.

If you’re dealing with OBD trouble code P3100, there are noteworthy generic symptoms that you can feel or see. Our team has written down a list below that will help you to better comprehend this very problem.

Common symptoms

• Excessively low fuel pressure
• Lean or rich exhaust
• Decreased fuel efficiency
• The light might remain on or light erratically as the DPF reprocesses. The engine will be slow on gaining speed.

As soon as you’ve learned the symptoms of your vehicle’s issue, it gets easier to specify this and start to solve it right away. Next thing on our list are some generic points to correct this problem with your vehicle’s performance.

• A specialty diagnostic CAN scanner will display pin values and an operating control module having not risked melting down any parts. 
• When turning the input shaft, by way of the engine, the electro magnetic input/turbine speed sensor utilizes the gaps between the splines to give voltage signal disruptions inside the circuit.
• This signal is methodically sent over to impacted control modules that use the data to achieve a variety of other jobs. 
• Many tools will be useful in achieving a diagnosis of this code.

Do not feel stressed out if your OBD Code is still bleeping on as our team is here to help you out. Take a glance at our upscale range of Powertrain Control Module, Crankshaft Position Sensor and even more. This way all your issues will disappear in a flash.

The P3100 Vehicle Trouble Code on cars with electronically regulated automatic transmissions is built with a 3-4-shift solenoid that responds by activating the hydraulic circuits to trigger clutches or bands that switch gears in the automatic transmission.

• As you turn on the ignition, the Service Engine Soon or Check Engine P3100 Light should be able to flash shortly, specifying the OBD system is ready to scan your car for any function breakdown. After a short flash, the light should remain off as you drive for a duration when no problems are found. You will be satisfied to be fully aware that your car is equipped with an early warning system that can save you time, money, and fuel to further assist with protecting the vehicle.
• As you press your foot down on the brakes, you expect your vehicle to soundly come to a slow down and stop all at once. Your foot exerts power onto the brake pedal that is helped by hydraulic pressure. The force of your foot is working a piston and caliper with the brake pads attached, a bonded abrasive and heat resistance metal or ceramic, to placing pressure onto the rotor.
• Power Steering Pressure (PSP) Switch Signal Malfunction is when the Powertrain Control Module (PCM) counts up all the times vehicle speed changes from zero to a standard speed. After a standard number of speed changes, the PCM waits for the PSP input that should have been changing. This sets the DTC if the change is not found. The vehicle being towed with a running Engine Power Steering Hydraulic poses a concern about needing repair, the DTC is not cleared, PSP switch/shorting bar is checked as damaged, SIG RTN circuit is open, PSP circuit is open or shorted to SIGRTN, PCM is checked as damaged, and if vehicle has been towed or power steering service has operated. Oversee PSP V PID when detecting wires for inconsistencies.

Common Mistakes When Diagnosing the P3100 Code

This problem is a result of the variable cylinder management system turning on and off during light throttle settings, at cruising speeds, or while driving on flat roads. The continuous switching results in too much oil usage and the error codes show up while oil pressure drops to an extent when it can’t perform any longer on the VCM system.

• High voltage system might not perform
• High voltage powertrain control module fails
