What to do if your Chevy ignition code is p1351?
What to do if your Chevy ignition code is p1351?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals. The cost of diagnosing the P1351 CHEVROLET code is 1.0 hour of labor.
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.
What causes a p1351 voltage to go up?
Below are some common causes of P1351-. Damaged, burnt, shorted, disconnected, or corroded wiring and connectors. Open circuits. Defective/damaged Crankshaft Position Sensors. Defective/damaged Camshaft Position Sensors (Where applicable) Abnormal system voltages caused by defects, malfunctions, or failures in the charging system.
What does p1351 stand for in OBD II?
END OF SPECIAL NOTES. OBD II fault code P1351 is a manufacturer specific code that most carmakers define as “Ignition Control Module Circuit Voltage”, or sometimes as “Ignition Control Module Circuit High Voltage”.
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
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.
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.
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.
How much does it cost to repair a p1351 Chevy?
The cost of diagnosing the P1351 CHEVROLET code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.
Where is the air injection fuse on a Chevy Blazer?
This is the first step in trying to diagnose the P0410 DTC on a Chevy Blazer and other vehicles. The air injection pump is part of the emissions system. While it is not shown on the video there is a 10 amp fuse in the same location I tested this and the fuse was fine.
What causes a p1351 circuit to short out?
Below are some common causes of P1351- Damaged, burnt, shorted, disconnected, or corroded wiring and connectors Abnormal system voltages caused by defects, malfunctions, or failures in the charging system Failed, or failing PCM.
