This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the temperature sensors inside the transmission aren't agreeing with each other about how hot the transmission fluid is.
The code P183B is triggered when the Transmission Control Module (TCM) detects a mismatch or correlation issue between the transmission fluid temperature sensor and the internal temperature sensor within the TCM.
The P183B code indicates a correlation error between the transmission fluid temperature sensor and the TCM's internal temperature sensor, particularly when the temperature is in a medium range. This could be due to a faulty sensor, wiring issues, or a malfunction within the TCM itself. The sensors are responsible for providing accurate temperature readings to ensure proper transmission operation.
• Check Engine Light is on
• Transmission may shift improperly
• Overheating transmission
• Reduced fuel efficiency
• Faulty transmission fluid temperature sensor
• Faulty TCM internal temperature sensor
• Wiring issues or poor connections
• Malfunctioning TCM
TCM: Transmission Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections to the sensors.
• Test the transmission fluid temperature sensor.
• Test the TCM internal temperature sensor.
• Repair or replace faulty wiring or connectors.
• Replace the transmission fluid temperature sensor.
• Replace the TCM internal temperature sensor.
• Reprogram or replace the TCM if necessary.
• OBD-II scanner
• Multimeter
• Socket set
$150 - $600
Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regular transmission fluid checks and changes.
• Routine inspection of wiring and connectors.
• Ensure TCM software is up to date.
Sensor Issue
• Avoid driving aggressively until the issue is resolved.
• Check transmission fluid levels regularly.
• Consult a professional mechanic for a thorough diagnosis.
Transmission and related components may be covered under powertrain warranty.
This code has been more prevalent in vehicles with higher mileage or those that have not had regular transmission maintenance.
Moderate – It is important to address this issue to prevent potential transmission damage.
Ignoring this issue could lead to transmission failure, which may result in unsafe driving conditions.
• Engine at operating temperature
• Vehicle in park or neutral
The transmission fluid temperature sensor is typically located on or inside the transmission housing.
Q: Can I drive with a P183B code?
A: It's possible to drive short distances, but it's best to get it checked soon to avoid transmission damage.
Q: How much does it cost to fix a P183B code?
A: Repair costs can range from $150 to $600, depending on the exact issue and vehicle model.
