OBD-II Code P068A: What It Is, Symptoms, Causes & How to Fix It with iCarsoft CR Ultra P
If your vehicle struggles to start, shuts off unexpectedly, or triggers the check engine light with OBD-II Code P068A—defined as “Powertrain Control Module (PCM)/Engine Control Module (ECM) Power Relay De-Energizing Too Early”—you’re facing a critical electrical issue that threatens reliability and safety. The PCM/ECM power relay is the “gatekeeper” of your vehicle’s brain, and premature de-energization cuts power to the module, disrupting essential functions. But you don’t need to overpay for dealer diagnostics: this guide breaks down everything you need to know about P068A, plus why the iCarsoft CR Ultra P diagnostic tool is the DIYer’s must-have to detect, troubleshoot, and clear this error code for good.
What Is OBD-II Code P068A?
OBD-II codes are universal alerts from your vehicle’s onboard systems when powertrain malfunctions occur. Specifically, P068A indicates the PCM/ECM power relay is turning off (de-energizing) earlier than expected—usually when the engine is still running or during startup.
The PCM/ECM power relay supplies consistent voltage to the vehicle’s main control module, which regulates engine performance, fuel injection, and ignition. When the relay de-energizes prematurely, the PCM/ECM loses power, causing hard starts, unexpected shut-offs, or even complete system failure. This issue is often linked to electrical faults but requires precise diagnosis to avoid misrepairs.
Common Symptoms of P068A
Watch for these red flags that P068A is affecting your vehicle:
-
Difficulty starting the engine (takes multiple cranks or fails to start)
-
Unexpected engine shut-offs while driving (highly dangerous!)
-
Illuminated Check Engine Light (MIL) – solid or persistent
-
Reduced engine power or sluggish acceleration
-
Intermittent electrical issues (e.g., dashboard lights flickering)
-
Vehicle stalls at idle or low speeds
-
Inability to restart the engine after shutdown
-
Warning messages for “power system fault” (on newer vehicles)
Top Causes of P068A
Pinpointing the root cause of P068A is critical to avoiding breakdowns—and a professional diagnostic tool simplifies this. Common triggers include:
-
Faulty PCM/ECM power relay (internal electrical failure or wear)
-
Damaged, frayed, or shorted wiring in the relay circuit
-
Loose, corroded, or disconnected electrical connectors for the relay
-
Low vehicle battery voltage or faulty alternator (insufficient power supply)
-
Malfunctioning PCM/ECM (rare, but possible if relay and wiring check out)
-
Blown fuse in the PCM/ECM power circuit
-
Water or debris damage to the relay or wiring (common in underhood locations)
-
Faulty ignition switch (interrupts power to the relay)

FAQ: Everything You Need to Know About P068A & iCarsoft CR Ultra P
What exactly does OBD-II Code P068A mean?
P068A indicates the PCM/ECM power relay is de-energizing too early—cutting power to the control module and causing starting/shutoff issues.
Is it safe to drive with P068A?
No—unexpected engine shut-offs while driving pose a serious safety risk. Stop driving immediately and fix it to avoid accidents or further damage.
Can I clear P068A without a diagnostic tool?
Disconnecting the battery resets the Check Engine Light temporarily, but P068A will return unless you fix the relay, wiring, or battery. A tool like the iCarsoft CR Ultra P is needed to identify the root cause.
Will the iCarsoft CR Ultra P work with my vehicle?
It’s compatible with most OBD-II compliant vehicles (1996+ US, 2000+ EU/Asian) including cars, trucks, SUVs, and vans. Check the product page for full brand/model coverage.
Do I need technical skills to use it?
No! It’s plug-and-play: connect to your vehicle’s OBD-II port (under the dashboard), turn on the ignition, and follow on-screen prompts to scan for P068A.
Will the iCarsoft CR Ultra P clear P068A permanently?
Yes—if you repair the root cause (e.g., replace relay, fix wiring, charge/replace battery). The tool resets the PCM/ECM, so the code won’t return if the issue is resolved.
How much money can I save with this tool?
Professional diagnostics for P068A cost $100–$350, plus $200–$1,000 in repair fees. The iCarsoft CR Ultra P pays for itself after one use and works for future electrical issues.
Where can I buy the iCarsoft CR Ultra P?
Purchase directly from the official iCarsoft website for genuine quality, worldwide shipping, and a 1-year warranty.
