P0792: Intermediate Shaft Speed Sensor A Circuit Range/Performance
The P0792 code indicates that the Powertrain Control Module (PCM) has detected an issue with the intermediate shaft speed sensor 'A' circuit, specifically that the signal is out of the expected range or not performing correctly. This sensor monitors the rotational speed of the intermediate shaft within the transmission, which is critical for proper shift timing and transmission operation. A fault can lead to erratic shifting, transmission slippage, or even complete transmission failure if ignored.
01. Most Common Causes
- Faulty intermediate shaft speed sensor
- Damaged or corroded wiring/connectors to the sensor
- Transmission fluid contamination or low fluid level
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Erratic or harsh shifting
- Transmission slipping or delayed engagement
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for additional codes and record freeze frame data.
Step 2: Inspect the intermediate shaft speed sensor and its wiring for damage, corrosion, or loose connections.
Step 3: Test sensor resistance and signal output with a multimeter; compare to manufacturer specs.
Step 4: Check transmission fluid level and condition; top off or replace if necessary.
Step 5: If sensor and wiring are okay, suspect internal transmission issues and consult a professional.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances with this code, as it can cause transmission damage. You may experience shifting problems that could leave you stranded.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for a sensor replacement, but if wiring repairs or transmission work is needed, it can be significantly higher.
