By Samuel The P1352 trouble code indicates a problem with the ignition coil "D" primary or secondary circuit in your Chevrolet.
This issue can cause symptoms like engine stalling, rough idling, or poor performance.
Faulty ignition coil, wiring issues, or a malfunctioning engine control module are possible causes of this trouble code.
To fix the problem, use a code reader, multimeter, and other tools to diagnose the issue, uncover the underlying cause, and take the necessary steps to repair your vehicle.
What does this Code Mean
Your vehicle's onboard diagnostics system has shown a P1352 code. This code is specific to Chevrolet vehicles.
It means there's a problem with the ignition coil "D" primary or secondary circuit. This could be due to a faulty ignition coil, a short circuit in the wiring, or a malfunctioning engine control module.
You need to investigate to find the root cause. This code doesn't usually harm the engine immediately, but it's still important to fix it as soon as possible to avoid damage or decreased performance.
What are the Symptoms
The symptoms of the P1352 code include:
- The engine stalls or is hard to start
- The engine idles rough
- The engine doesn't perform well
- The Check Engine Light comes on
What are the Causes
The P1352 code in your Chevrolet can be caused by:
Faulty ignition coils, worn-out spark plugs, or a malfunctioning crankshaft position sensor.
These problems can make your engine misfire, leading to poor performance and bad fuel efficiency.
Other causes of the P1352 code include:
Faulty fuel injectors that are clogged or dirty
A malfunctioning engine control module (ECM)
Low fuel pressure due to a faulty fuel pump or clogged fuel filter
Worn-out or damaged engine bearings that disrupt crankshaft position sensor operation
What Tools are Needed to Diagnose
To diagnose the P1352 code in your Chevrolet, you need these tools:
- A code reader or scan tool to get and clear trouble codes
- A multimeter to measure voltage and resistance in the ignition system
- A fuel pressure gauge to test fuel system pressure
- A wiring diagram or repair manual for your specific Chevrolet model
How to fix Step by Step
Step 1: Connect your OBD-II scanner to your vehicle's onboard computer and retrieve the trouble code.
Step 2: Check the fuel trim data to identify which bank of the engine is affected.
Step 3: Use a fuel pressure gauge to test the fuel pressure, ensuring it's within the recommended specifications.
Step 4: If the pressure is low, inspect the fuel filter and replace it if necessary.
Then, check the fuel injectors for any signs of clogging or malfunction.
Clean or replace them as needed.
Step 5: Clear the trouble code and test drive your vehicle to ensure the issue is resolved.
What are the Common Diagnosis Mistakes
Common diagnosis mistakes include:
- Not clearing the code and test driving the vehicle after repairs, which can cause repeat issues.
- Failing to check for other related trouble codes.
- Overlooking basic checks, such as ensuring the battery is fully charged and the ignition system is functioning properly.
- Not consulting the repair manual or online resources for specific guidance on diagnosing and repairing the P1352 code.
What is the Repair Cost
The repair cost for the P1352 code can range from $100 to $2,000, depending on the specific repair needed.
Fuel injector replacement costs $100 to $300 per injector, plus $100 to $200 for labor.
Wiring repairs can cost $500 to $1,000, and engine control module replacement can cost $1,000 to $2,000.
Can I drive safely with this code?
No, it's not safe to drive with a P1352 code.
This code means your fuel injector circuit has a problem, which can cause engine misfires, poor performance, and damage to your catalytic converter.
Stop driving and have a mechanic fix the issue to avoid further problems.
