Overview
The control module stored P0992 because it detected a problem with: Transmission Fluid Pressure Sensor/Switch F Circuit.
P0992 relates to Transmission Fluid Pressure Sensor/Switch F Circuit. Use a quality scan tool, follow wiring diagrams for your vehicle, and confirm tests before replacing expensive parts.
What does the P0992 code mean?
When P0992 is set, the vehicle’s diagnostics detected an issue described as: Transmission Fluid Pressure Sensor/Switch F Circuit. In practice, the ECM/PCM (and related modules) compare sensor inputs, commanded outputs, and self-tests for that subsystem. The exact repair depends on whether the fault is wiring-related, component-related, or a rationality/performance issue for this circuit or system.
Common symptoms of P0992
- Limp mode or limited gears
- Slipping or flaring
- Harsh or delayed shifting
- Transmission warning indicator
- Poor acceleration
- Check engine light
Possible causes
- Fault affecting Transmission Fluid Pressure Sensor/Switch F Circuit (wiring, connector, or component)
- Electrical fault in the monitored circuit
- Control module strategy or calibration issue
- Component failure in the described system
- Control module or software calibration issue (less common—verify tests first)
- Past repairs or aftermarket parts causing out-of-spec operation
How to diagnose P0992
- Scan for P0992 and review freeze frame / pending codes for related faults
- Inspect connectors and wiring related to: Transmission Fluid Pressure Sensor/Switch F Circuit
- Compare live data and commanded vs actual values for the affected system (per service information)
- Perform circuit tests appropriate to the fault type (continuity, voltage, resistance) before replacing parts
- Confirm power and ground integrity at the relevant module or sensor
- After repair, clear DTCs and verify under the conditions that originally set P0992
Tip: Use a scan tool that shows live data and freeze frame for the conditions when the code set.
Severity of code P0992
Moderate: Have this code diagnosed soon; ignoring it can lead to worse fuel economy, repeat failures, or secondary damage.
Can you drive with P0992?
Short trips may be okay if the vehicle feels normal, but have it diagnosed—especially if performance, safety warnings, or overheating are present.
Avoid heavy acceleration, towing, or long highway drives until the cause of P0992 is confirmed and repaired.
How to fix it (step-by-step)
- Start with visual inspection and connector cleaning/tightening where needed
- Confirm failure mode with testing—avoid swapping parts without evidence
- Repair wiring or replace the failed component per manufacturer procedure
- Clear faults, run relearns if required, and road test to confirm
Repair & fix options
- Clear codes and verify with drive cycle
- Inspect connectors and wiring first
- Test component against service limits
- Clear codes and verify repair with a drive cycle and readiness where applicable
- Reinspect related monitors if the code returns after repair
Typical repair cost
$150 – $4,500+ depending on cause

How to help prevent P0992 in the future
- Fix new codes early before secondary damage or catalyst stress
- Keep connectors clean and secure; address rodent or water intrusion in harnesses
- Use the correct fluids/parts for your vehicle and service intervals
- Avoid ignoring pending codes after battery work or repairs
When to see a mechanic
Schedule diagnosis if the check engine light is on, drivability is worse, or you notice new noises, smells, or warning lamps. For safety-related (SRS/ABS) or overheating symptoms, prioritize a qualified shop immediately.
Common mistakes when diagnosing P0992
- Replacing sensors/modules without verifying wiring and reference voltages
- Ignoring related codes that identify the real root cause
- Clearing codes without a verification drive cycle
Common vehicles & notes for P0992
- Nissan / Hyundai models (common examples—verify for your vehicle)
- Kia / Mazda applications vary by engine and model year
- Many other makes—this is a standardized OBD-II definition: Transmission Fluid Pressure Sensor/Switch F Circuit
P0992 is reported across many platforms including Nissan, Hyundai, Kia, Mazda. Always use VIN-specific service information for testing limits and calibration steps.
Frequently asked questions
What does P0992 mean?
P0992 indicates a fault involving Transmission Fluid Pressure Sensor/Switch F Circuit, based on what the control module detected during self-tests or live monitoring.
Is it safe to drive with P0992?
If the vehicle runs normally and no warning lights are flashing, short trips may be reasonable—but avoid ignoring symptoms like misfire, overheating, ABS/SRS warnings, or major loss of power.
How much does it cost to fix P0992?
Typical repairs often fall in the ranges shown on this page, but final cost depends on labor rate, parts quality, and whether the issue is wiring vs. a major component.
What is the most common cause of P0992?
Most shops start with wiring/connectors and the directly monitored component for “Transmission Fluid Pressure Sensor/Switch F Circuit,” then expand testing if the fault returns.
Will P0992 clear itself?
It may become intermittent, but if the underlying fault remains, the code will usually return—especially after a drive cycle.
Can a weak battery cause P0992?
Low system voltage can cause odd sensor/module behavior, but you should still validate the actual DTC and perform normal circuit/component tests.
