Bertone Freeclimber B2594 Engine Trouble Code
What is Bertone Freeclimber B2594?
With Bertone Freeclimber B2594, you may drive for several weeks with a malfunctioning MAF sensor, but expect decreased fuel economy and eventual stalling. Shop replacement costs $240–$400 depending on vehicle. The labour is straightforward, with most cost from the part itself.
B2594 on the Bertone Freeclimber
Diesel variants of the Bertone Freeclimber trigger B2594 most often due to swirl flap actuator failure. The plastic actuator arm breaks and the flap defaults to the closed position, causing severe intake restriction and the associated fault flag.

How to Fix Bertone Freeclimber B2594
Diagnostic Steps:
Poor running symptoms align with MAP sensor malfunction. In some cases, a faulty MAP sensor will not trigger a code. The issue may represent separate wiring concerns requiring individual diagnosis.
Repair Solution:
Firing order is engineered to minimise vibration. Altering firing order results in mistimed ignition and poor engine operation. Consult vehicle-specific repair manual for correct firing order.
Technical Notes:
B2594 on electronically controlled automatic transmissions relates to shift solenoid operation. The solenoid actuates hydraulic circuits controlling clutches or bands for gear changes.
Bertone Freeclimber B2594 Repair Cost
A Bertone Freeclimber B2594 fault caused by ignition coil failure costs roughly $90–$160 per coil including labour. Replacing all coils simultaneously — rather than one at a time — is recommended because coils typically age at similar rates. This preventive approach keeps total cost below $500.
B2594 Description
B2594 engine trouble code is related to Timing Reference High Resolution Signal A Too Many Pulses.
Main Cause
The primary reason for B2594 OBD-II Engine Trouble Code is: Fuel Composition Sensor Circuit Malfunction.
Common B2594 Misdiagnosis on the Bertone Freeclimber
The Bertone Freeclimber purge valve for the EVAP system is located in an area prone to heat damage. It is often overlooked in favour of replacing the carbon canister ($120–$200) when the valve itself ($25–$50) is the failed component for B2594.
DIY Repair Guide: B2594 on Bertone Freeclimber
When replacing sensors on the Bertone Freeclimber, always use anti-seize compound on the thread and dielectric grease on the electrical connector. This simple habit prevents the most common causes of sensor-related callbacks after repair.
Preventing B2594 on the Bertone Freeclimber
To keep the Bertone Freeclimber free of recurring B2594 faults, change the engine oil every 5,000–7,500 miles using a grade specified by Bertone. Oil viscosity directly affects VVT actuator response, and using the wrong grade is one of the most avoidable causes of this code.
Frequently Asked Questions — Bertone Freeclimber B2594
A: Not always. Across model years, Bertone revised sensor specifications, wiring paths, and ECU calibrations. Always confirm the repair procedure matches your specific vehicle's production year and engine code, as parts and labour times can vary significantly.
