Ssangyong Rexton P273D Engine Trouble Code
What is Ssangyong Rexton P273D?
Ssangyong Rexton P273D code can indicate a faulty oxygen sensor, which may eventually damage the catalytic converter (repair cost: $2,000–$2,200). Professional diagnosis costs around $200–$210. Oxygen sensors are often straightforward to replace — check your owner's manual for location and instructions. This issue should be addressed promptly to prevent further damage.
P273D on the Ssangyong Rexton
Transmission-mounted speed sensors on the Ssangyong Rexton share a ground path with the engine control module. A corroded ground point on the transmission bell housing generates electrical noise that the ECU misinterprets as a P273D fault condition.

How to Fix Ssangyong Rexton P273D
Diagnostic Steps:
Regarding P273D, carefully inspect the wire harness near the intake manifold bracket, best accessed from below near the oil filter. Look for chafing, pinching, or damaged insulation.
Repair Solution:
Verify all electrical connections are clean and tight. Check for damaged wiring, especially in high-heat or high-vibration areas. Use manufacturer wiring diagrams for accurate diagnosis.
Technical Notes:
P273D on electronically controlled automatic transmissions relates to shift solenoid operation. The solenoid actuates hydraulic circuits controlling clutches or bands for gear changes.
Ssangyong Rexton P273D Repair Cost
Torque converter clutch solenoid replacement on the Ssangyong Rexton — relevant for owners who tow regularly — costs $280–$480. A full transmission fluid change ($120–$160) at the same service is recommended because contaminated fluid accelerates solenoid wear.
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 Rexton
When Ssangyong Rexton presents P273D with a concurrent coolant temperature DTC, technicians sometimes replace the thermostat rather than the coolant temperature sensor (CTS). The CTS is a $15–$25 component; the thermostat job carries 1–2 hours of additional labour.
DIY Repair Guide: P273D on Ssangyong Rexton
Battery terminal cleaning on the Ssangyong Rexton is a 5-minute job that resolves a surprising number of P273D intermittents. Use a wire brush and a bicarbonate of soda solution to clean corrosion, then apply a thin coat of petroleum jelly to the terminals after refitting.
Preventing P273D on the Ssangyong Rexton
Verify that the Ssangyong Rexton engine air box lid clips are fully seated after any air filter service. An unsealed air box is a direct path for unmetered air past the MAF sensor and is an extremely common — and extremely embarrassing — cause of P273D.
Frequently Asked Questions — Ssangyong Rexton P273D
A: Not always. Across model years, Ssangyong 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.
