What does the p1351 code on a Chevy mean?

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.

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.

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.

How much does it cost to diagnose a p1351 Chevy code?

The cost of diagnosing the P1351 CHEVROLET code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. When is the P1351 CHEVROLET code detected? The Ignition Control Module (ICM) has independent power and ground circuits.

What is the p1351 ignition control module voltage?

P1351 – Ignition Control Module Circuit Voltage Trouble Code Fault Location P1351 Ignition Control Module Circuit Voltage

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 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”.

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.

How to diagnose a p1351 Chevrolet ignition circuit?

Start by checking 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 connector’s pins. The cost to diagnose the P1351 CHEVROLET code is 1.0 hour of labor.

Where are the spark plugs on a p0174 DTC?

This bank is the one on the driver side of the engine. Bank 2: A P0174 DTC tells you that bank 2 is the one having the issue. Bank 2 is the engine bank that holds the spark plugs for cylinders 2, 4, and 6 (V6 4.3L). Cylinders 2, 4, 6 and 8 (V8 5.0L, 5.7L). This bank is the one on the passenger side of the engine.

What does the low voltage code p0151 mean?

Essentially the same as P0136 and P0137 and P0131 , a P0151 code refers to the first oxygen sensor on Bank 2 . P0151 means the O2 oxygen sensor’s voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 2 Sensor 1 is located in front of the catalytic converter.

What is the misfire code on a Chevy Silverado?

P0131, P0151, and misfire code. 1996 Chevy Silverado, V8, 5.7L, 130k miles The engine runs and idles ok. But when I accelerate hard, it lacks power at higher RPM (5000). At this point, the dummy light starts blinking (according to the manual it means misfire) and then goes steady after normal driving.

What causes a misfire in a Ford P0300?

Low fuel pressure can cause intermittent misfires on multiple cylinders. When the pressure is below the specification, the engine does not receive the proper amount of fuel and will start to lean misfire. The fuel pump or fuel pressure regulator could be the source of the low fuel pressure.

How can I tell if my car has a P0300 code?

Use FIXD to scan your vehicle to verify P0300 is the only code present. If other codes are present, they must be addressed first. Check for loose connectors at the ignition coils or for damaged wiring. Look for loose engine ground wires as well.

What does P0300 mean on a spark plug?

Many times, P0300 occurs when there are worn out spark plugs, spark plug wires, or a faulty ignition coil. P0300 should be repaired immediately.

When does a misfire occur in an engine?

A misfire occurs when an insufficient amount of fuel is burned in a cylinder. The efficient burning of fuel is essential to engine operation as the combustion of fuel is what provides the energy to power the engine.
