Suzuki Hustler B2594 Engine Trouble Code
What is Suzuki Hustler B2594?
Suzuki Hustler B2594 indicates potential catalytic converter failure. If completely failed, your vehicle may not run properly and fuel economy will suffer significantly. Average replacement cost is $2,000–$2,140. This repair requires professional service and should not be delayed.
B2594 on the Suzuki Hustler
The Suzuki Hustler features a sequential multi-port fuel injection (SMFI) system where injector timing is tightly synchronised with the crankshaft signal. Wear on the crankshaft reluctor ring teeth produces signal dropout events that accumulate and eventually trigger B2594.

How to Fix Suzuki Hustler B2594
Diagnostic Steps:
The catalytic converter has oxygen sensors before and after it. When warm and in closed-loop mode, the upstream O2 sensor reading should fluctuate, while downstream should remain steady.
Repair Solution:
Power steering pressure switch monitors system operation. If pressure changes are not detected after calibrated speed transitions, this DTC sets. Verify PSP switch operation and check for circuit opens or shorts.
Technical Notes:
B2594 DTCs can be triggered by upstream issues. For example, a dirty MAF sensor may cause incorrect fuel-trim adjustments, leading oxygen sensors to report mixture problems. Address root causes first.
Suzuki Hustler B2594 Repair Cost
When B2594 appears on a Suzuki Hustler, a camshaft position sensor swap costs $140–$260 all-in. This is one of the more affordable sensors on this platform. If the wiring harness is also damaged, add $60–$90 for harness repair or section replacement.
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 Suzuki Hustler
Replacing the PCM/ECU on the Suzuki Hustler for a persistent B2594 is a last-resort action that is often performed prematurely. Statistically, less than 2% of B2594 faults on this platform originate in the ECU; wiring, sensors, and mechanical causes account for the remainder.
DIY Repair Guide: B2594 on Suzuki Hustler
The fuel pressure test on the Suzuki Hustler requires a Schrader-valve type fuel pressure gauge ($25–$40) connected to the fuel rail test port. With the ignition ON (engine off), pressure should hold above 30 PSI for two minutes. A rapid drop confirms a leaking injector or failing regulator as the root cause of B2594.
Preventing B2594 on the Suzuki Hustler
Scheduled inspection of the Suzuki Hustler air filter every 15,000 miles can prevent the intake restriction that leads to B2594. A blocked filter forces the engine to run rich, stressing the catalytic converter and ultimately storing fault codes.
Frequently Asked Questions — Suzuki Hustler B2594
A: If your Suzuki Hustler is within the factory powertrain warranty period (typically 3–5 years or 60,000–100,000 miles depending on region and generation), B2594 repairs caused by component defects should be covered. Bring your service history to the dealer appointment.
