P0967 Code: Solenoid B Circuit High Diagnosis

1What Does the P0967 Code Mean?

The P0967 code means Pressure Control Solenoid B Control Circuit High. It names a monitored result, not a guaranteed failed part. The reporting module, suffix and companion faults determine the relevant test branch.

P0967 concerns the electrical control circuit for the transmission's B pressure-control solenoid. The letter is an OEM circuit identifier, not a universal location in a valve body. Controller-driver feedback, supply and load behavior must be distinguished from actual line pressure and shift quality.

High describes the monitored circuit condition. The vehicle may also change hydraulic pressure as a failsafe response, but that is a separate observation.

GM bulletin 20-NA-120 lists P0967 within a specific CVT diagnostic context. That example does not turn every high control-circuit fault into an internal transmission failure; match the transmission and bulletin applicability before following its inspection route.

This is a source-based diagnostic guide, not a record of a vehicle tested by our team. The checks below explain how to separate evidence for pressure-control solenoid B high circuit feedback from assumptions about replacement parts.

Read the stored wording exactly as the vehicle reports it. A short generic label can hide a manufacturer suffix, a circuit-direction detail, a bank or sensor identifier, or a setup condition that changes the first test. Save that wording before clearing the record so the diagnostic path can be repeated if the fault returns.

2P0967 Symptoms and Likely Causes

P0967 symptoms depend on fault status and the fallback strategy. Record what the driver and modules reported. A symptom list is not a parts list.

Look for patterns rather than isolated clues. A current fault with matching freeze-frame data deserves a different priority than an old history fault found during unrelated service. Companion codes can point to a shared feed, ground, connector, fluid state, mechanical path or controller condition, but they still need the same evidence-based separation.

Practical cause-checking order

• Identify the monitored path: Map solenoid B, driver type and harness connections for the exact transmission.
• Inspect accessible evidence: Inspect external connectors, fluid ingress, internal harness access and terminal retention.
• Compare command and response: Test supply and control feedback for a high classification using OEM loading and isolation rules.
• Test the suspect branch: Compare solenoid command or current data with measured circuit behavior.
• Confirm before replacement: Investigate hydraulic or controller issues only after the electrical branch is understood.

3How Serious Is P0967, and Can You Drive?

The P0967 code alone cannot establish a safe driving distance. Follow the owner’s manual and arrange diagnosis promptly. Stop if the transmission slips, engages violently, overheats or loses safe propulsion. A history record with normal operation and an active fault with a safety symptom need different responses.

Record temperature, load, speed, start state and recent service. Do not reproduce a severe symptom on public roads; another warning can make the situation more urgent. If the vehicle enters a reduced-power strategy, develops abnormal noise, leaks fluid, overheats or shows a red stop warning, the safety condition overrides any plan to complete a drive cycle.

Secure the vehicle and follow lifting and hot-fluid precautions. Do not energize transmission solenoids directly or perform an active test while someone is beneath the vehicle.

4How to Diagnose P0967 in the Right Order

1. Save the transmission event

   Record code suffixes, module voltage, gear, fluid temperature, shift complaints and all companion pressure-control faults. Avoid clearing evidence to temporarily restore shifting.

2. Identify solenoid B and its driver

   Use the transmission code and VIN diagram to locate the correct load and control wire. Confirm whether the solenoid is separately serviceable or part of an integrated assembly.

3. Inspect the connector path

   Look for fluid intrusion, pin damage, loose locks and harness chafing, especially after valve-body work. Follow the service procedure before disconnecting internal wiring.

4. Test high circuit feedback

   Measure the supply and driver circuit at the prescribed key state and load. Do not infer short-to-voltage or an open load from the word high alone; the driver design determines those branches.

5. Compare command, current and pressure

   Use available scan commands only when supported and safe. Correlate current or waveform evidence with the specified hydraulic test if needed; scan pressure alone cannot prove mechanical pressure.

6. Verify the repaired branch and shifts

   Repair the proven circuit or solenoid, complete required fluid and adaptation procedures, and verify under the correct temperature range. Recheck current and pending faults and compare the original shift event.

5P0967 Repairs and Typical Costs

The correct P0967 repair follows the failed test. Wiring, a physical repair, a proven component, software and controller work are different outcomes. Do not replace an assembly from the generic code alone.

Recheck installation and required setup after repair. An integrated valve body may require configuration or adaptation. Include those operations in a quote only when the applicable repair procedure calls for them.

A useful estimate should name the failed branch, not just the code. Ask whether the shop found an open, short, biased signal, missing supply, poor ground, mechanical restriction, fluid condition, calibration requirement or module fault. That wording makes the recommendation auditable and protects against replacing several unrelated parts after one stored DTC.

When the failed branch is still uncertain, pay for diagnosis before authorizing parts. A careful proof step is usually less disruptive than repeating repairs after the same monitor sets again.

These are alternative repair paths, not prices to add together. Request a VIN-specific quote separating diagnosis, parts, labor, fluids, taxes, required setup and verification. Ask which failed test supports the proposed repair and whether warranty coverage applies.

6Using iCarsoft CR Pro S for P0967

On a supported vehicle, iCarsoft CR Pro S can retrieve accessible module faults, save available freeze frame, display ECU-provided live data and create a diagnostic report. For P0967, preserve the original evidence and compare related modules before clearing an erasable record.

Use the report as a record of what the controller knew at the time. It helps compare code status, freeze-frame conditions and available PIDs before and after repair. It does not replace the wiring diagram, service procedure, safe access instructions or physical measurement required to prove the failed branch.

The official product page describes supported full-system diagnostics, available live data, freeze frame and diagnostic reports; exact controller coverage and active tests depend on the VIN and software. Confirm the requested function by VIN before purchase. Follow OEM prerequisites and stop for abnormal operation.

7Verify the P0967 Repair

After repair, verify connectors, harness clearance, setup and controller supply. Save post-repair findings, then clear only erasable records through the approved procedure. Battery disconnection is not a repair.

Run the manufacturer's applicable verification conditions in a safe workshop or route. Compare the original operating state with current data for the pressure-control solenoid B high circuit feedback, and check current and pending faults in related modules. One clean start or idle period does not prove that every conditional monitor has completed.

Document what changed between the first scan and the verification scan. Useful notes include module status, current versus history state, freeze-frame differences, whether the same enabling conditions returned, and whether a relearn or service function was accepted. Preserve the original diagnostic fault order. This record helps separate an incomplete monitor from a repair that failed under the same conditions.

If P0967 returns, compare its suffix, status, failure order and operating conditions with the saved baseline before replacing another part. Revisit the failed branch and inspect anything disturbed. Keep mechanical repair, monitor completion, readiness and local inspection eligibility as separate outcomes.
