Ssangyong Kyron P273D Engine Trouble Code
What is Ssangyong Kyron P273D?
The Ssangyong Kyron P273D check-engine light can indicate issues ranging from minor (loose gas cap) to serious (catalytic converter failure). Professional diagnostic scanning at a dealer or shop will identify the exact cause and required repairs.
P273D on the Ssangyong Kyron
Service bulletins for the Ssangyong Kyron specifically mention P273D as a symptom of failed purge solenoid valves in the EVAP system. The solenoid body on this platform degrades in high-humidity environments and should be inspected whenever this code appears.

How to Fix Ssangyong Kyron P273D
Diagnostic Steps:
Check if fuel pump primes when key is turned to ON. Measure fuel pressure and verify bright white-blue spark at all plugs. Also verify mechanical timing alignment.
Repair Solution:
Excessive air inflow may result from vacuum leaks, dirty sensors, or EGR valves not closing properly. Insufficient fuel can stem from dirty injectors, clogged filters, weak fuel pump, or leaking pressure regulator.
Technical Notes:
P273D 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.
Ssangyong Kyron P273D Repair Cost
A fuel pressure regulator replacement on the Ssangyong Kyron runs $180–$320 at a specialist. Fuel system work requires depressurisation procedures, so this is not typically a DIY job. Some workshops include a full fuel injector flow test (value: $80) at no extra charge.
P273D Description
P273D engine trouble code is related to System Malfunction.
Main Cause
The primary reason for P273D OBD-II Engine Trouble Code is: Fuel Rail Pressure Sensor Circuit Malfunction.
Common P273D Misdiagnosis on the Ssangyong Kyron
The Ssangyong Kyron 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 P273D.
DIY Repair Guide: P273D on Ssangyong Kyron
For the mechanically confident Ssangyong Kyron owner, a DIY MAF sensor clean is a rewarding first step for P273D. Use a dedicated MAF sensor cleaner spray — not brake cleaner, which damages the sensing element — and allow the sensor to dry for 30 minutes before reinstallation.
Preventing P273D on the Ssangyong Kyron
The Ssangyong Kyron coolant temperature sensor plays a role in fuel enrichment during warm-up. Replacing it as a precaution at 80,000 miles ($25–$40 DIY) prevents the faulty cold-start enrichment that can lead to P273D.
Frequently Asked Questions — Ssangyong Kyron P273D
A: If your Ssangyong Kyron is within the factory powertrain warranty period (typically 3–5 years or 60,000–100,000 miles depending on region and generation), P273D repairs caused by component defects should be covered. Bring your service history to the dealer appointment.
