What does code P1351 mean?
What does code P1351 mean?
What does this mean? When is the code detected? The Powertrain Control Module (PCM) detects an open in the Ignition Control Module (ICM) Possible symptoms – Engine Light ON (or Service Engine Soon Warning Light) P1351 Gmc Description The Ignition Control Module (ICM) has independent power and ground circuits.
What is ignition control circuit?
An ignition timing control system is described for an internal combustion engine having an ignition circuit, an ignition coil, and a spark plug, for applying a trigger signal to the ignition circuit which, in response to the trigger signal, applies a high-voltage pulse to the ignition coil for driving the spark plug.
How do you test an ignition control module?
Connect the ground lead from the 12-volt test light to the negative terminal on the ignition coil. Have your partner crank the engine over several times. Your test light should flicker on and off. If so, your module is working properly and no further testing is necessary.
What does Engine code P1345 mean?
Error Code P1345 is defined as Crankshaft Position-Camshaft Position Correlation. This error code is a manufacturer-specific trouble code, meaning it does not apply to all vehicles makes. Rather, it applies only to specific vehicle makes, such as Audi, GM (Chevrolet/GMC), Isuzu, Lexus, Mazda, Toyota, and Volkswagen.
How do I know if my ignition module is bad?
Signs of a Bad Ignition Module
- Acceleration Issues. The vehicle may shake, vibrate or jerk when the gas pedal is pressed. There may be hesitation or lack of power during increases in speed.
- Temperature Problems. A faulty ignition module can cause a vehicle to overheat.
- No Power. The engine may turn over without starting.
What happens when ignition control module goes bad?
A faulty ignition module can affect ignition timing, resulting in an engine that misfires and runs rough. The engine may also run well at low speed, but won’t accelerate well. 3. Stalling: A failing ignition module can occasionally prevent the engine from getting spark, causing it to stall.
What are the signs of a bad ignition control module?
As a driver, you must keep an eye on any symptom of a bad ignition control module. These symptoms include engine stalling, engine misfiring, engine running rough, and difficulty starting.
What does the p1351 code on a Chevy mean?
P1351 CHEVROLET Meaning The Ignition Control Module (ICM) has independent power and ground circuits. The circuits between the ICM and the Powertrain Control Module (PCM) consists of the following circuits: -The ignition control (IC) timing signal
When does the PCM set the code p1351?
Nonetheless, regardless of the cause of the problem, the PCM will set code P1351 and illuminate a warning light when it detects an abnormal voltage in the control circuit of the Ignition Control Module. The image below shows a much-simplified schematic of a typical DIS ignition system.
Can a leaking fuel pressure regulator set the p1351 code?
If it doesn’t hold, then you’ll need to check for a leaking injector causing a rich condition which would require a long crank time to clear out the excess fuel (which sets the code intermittently) before the engine willl start. It’s possible for the fuel pressure regulator to leak only when the engine is running. I’ve personally experienced that.
What are the symptoms of a p1351 problem?
Apart from a stored trouble code and possibly an illuminated warning light, the typical symptoms of P1351 are largely make and model specific and much depends on the exact nature of the problem. Some applications might exhibit severe driveability issues, while on others the only immediately apparent symptom may be a no-start condition.
