Ignition Coil B Primary Control Circuit/Open
AI status
Completed
Completed
100%
Causes
- Open or short in the coil B primary wiring (broken wire, corroded connector)
- Poor connector pin contact or corrosion at the coil or wiring harness
- Failed ignition coil (internal open or short in the coil primary)
- Faulty ignition driver/transistor inside the ECM/ignition module
- Intermittent wiring issue (chafing, water intrusion)
- Battery or charging system low voltage affecting coil drive
Symptoms
- Check Engine Light (MIL) ON with stored P0352 code
- Rough idle, misfire or reduced power under load
- Occasional or persistent misfire on the cylinder served by coil B
- Hard starting or extended cranking time
- Engine may run in limp or reduced power mode
What to check
- Read freeze-frame data and live PID related to misfires and coil control outputs using a scan tool
- Record which cylinder is associated with coil B (consult vehicle wiring/repair manual)
- Inspect coil B connector and wiring for corrosion, damage, loose pins or water ingress
- Check battery and charging system voltage (low supply can affect coil drive)
- Swap coil B with an identical coil from another cylinder and see if the code follows the coil (moves to the other coil code)
- Backprobe coil connector while cranking/with scan tool commanding coil to fire and observe control signal
Signal parameters
- Primary supply (battery) voltage present at coil power terminal with key ON (typically ~12V)
- ECM/ignition driver produces a pulsed ground (or switched 12V on some systems) to the coil when cranking/running
- Primary coil resistance (varies by application) — low ohm value for primary winding, verify against vehicle spec
- No continuity (open) or near-zero (short) between primary circuit and expected reference indicates fault
Diagnostic algorithm
- Confirm code and note freeze-frame/live data. Identify which cylinder/connector is “coil B” per vehicle documentation.
- Visual inspection: with ignition OFF, inspect coil B connector, wiring harness, and engine grounds for damage, corrosion, or looseness. Repair obvious issues and clear codes.
- Swap test: swap coil B with another identical coil. Clear codes and re-run. If code follows coil to the new cylinder, suspect the coil. If code stays with the same circuit/cylinder, suspect wiring/ECM.
- Measure supply: with ignition ON, verify battery voltage at coil power terminal. If missing, trace power feed and fuse/relay.
- Check control signal: backprobe the coil control pin while cranking/commanding a fire. Expect a pulsed signal (switch to ground or +12V depending on design). Absence indicates open or failed driver.
- Resistance checks: with coil disconnected, measure primary and secondary resistance and compare to spec. An open primary indicates a bad coil.
- Wiring continuity: with power removed, check continuity from coil control pin back to the ECM connector pin. Check for short to battery (+) and short to ground.
- If wiring and coil test good but no drive signal at coil, suspect ECM/ignition driver. Before ECM replacement, re-check grounds, harness repair, and consult manufacturer service information for driver testing.
- After repair, clear codes and perform a road/test run to verify the code does not return and drivability is restored.
Likely causes
- Damaged connector or pin at coil B
- Broken or shorted coil B primary wire to battery or ground
- Failed coil B primary winding
- ECM driver transistor failed for coil B
Fault status
Status
P0352 — Ignition Coil B Primary Control Circuit/Open: ECM detected an open or absent control signal to the primary circuit of coil B. May cause misfire and MIL illumination.
Repair difficulty: Medium

Ignition - faulty
AI status
Completed
Completed
100%
Causes
- Open or short in the coil B primary wiring (broken wire, corroded connector)
- Poor connector pin contact or corrosion at the coil or wiring harness
- Failed ignition coil (internal open or short in the coil primary)
- Faulty ignition driver/transistor inside the ECM/ignition module
- Intermittent wiring issue (chafing, water intrusion)
- Battery or charging system low voltage affecting coil drive
Symptoms
- Check Engine Light (MIL) ON with stored P0352 code
- Rough idle, misfire or reduced power under load
- Occasional or persistent misfire on the cylinder served by coil B
- Hard starting or extended cranking time
- Engine may run in limp or reduced power mode
What to check
- Read freeze-frame data and live PID related to misfires and coil control outputs using a scan tool
- Record which cylinder is associated with coil B (consult vehicle wiring/repair manual)
- Inspect coil B connector and wiring for corrosion, damage, loose pins or water ingress
- Check battery and charging system voltage (low supply can affect coil drive)
- Swap coil B with an identical coil from another cylinder and see if the code follows the coil (moves to the other coil code)
- Backprobe coil connector while cranking/with scan tool commanding coil to fire and observe control signal
Signal parameters
- Primary supply (battery) voltage present at coil power terminal with key ON (typically ~12V)
- ECM/ignition driver produces a pulsed ground (or switched 12V on some systems) to the coil when cranking/running
- Primary coil resistance (varies by application) — low ohm value for primary winding, verify against vehicle spec
- No continuity (open) or near-zero (short) between primary circuit and expected reference indicates fault
Diagnostic algorithm
- Confirm code and note freeze-frame/live data. Identify which cylinder/connector is “coil B” per vehicle documentation.
- Visual inspection: with ignition OFF, inspect coil B connector, wiring harness, and engine grounds for damage, corrosion, or looseness. Repair obvious issues and clear codes.
- Swap test: swap coil B with another identical coil. Clear codes and re-run. If code follows coil to the new cylinder, suspect the coil. If code stays with the same circuit/cylinder, suspect wiring/ECM.
- Measure supply: with ignition ON, verify battery voltage at coil power terminal. If missing, trace power feed and fuse/relay.
- Check control signal: backprobe the coil control pin while cranking/commanding a fire. Expect a pulsed signal (switch to ground or +12V depending on design). Absence indicates open or failed driver.
- Resistance checks: with coil disconnected, measure primary and secondary resistance and compare to spec. An open primary indicates a bad coil.
- Wiring continuity: with power removed, check continuity from coil control pin back to the ECM connector pin. Check for short to battery (+) and short to ground.
- If wiring and coil test good but no drive signal at coil, suspect ECM/ignition driver. Before ECM replacement, re-check grounds, harness repair, and consult manufacturer service information for driver testing.
- After repair, clear codes and perform a road/test run to verify the code does not return and drivability is restored.
Likely causes
- Damaged connector or pin at coil B
- Broken or shorted coil B primary wire to battery or ground
- Failed coil B primary winding
- ECM driver transistor failed for coil B
Fault status
Status
P0352 — Ignition Coil B Primary Control Circuit/Open: ECM detected an open or absent control signal to the primary circuit of coil B. May cause misfire and MIL illumination.
Repair difficulty: Medium
Diagnostic time: 0.5-2.0 hours
