Saab 750 C1396 Engine Trouble Code
What is Saab 750 C1396?
Saab 750 C1396 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.
C1396 on the Saab 750
On the Saab 750, a triggered C1396 code almost always warrants an immediate inspection of the exhaust gas recirculation (EGR) system. Carbon build-up inside the EGR valve is a well-documented root cause for this platform.

How to Fix Saab 750 C1396
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:
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:
C1396 on electronically controlled automatic transmissions relates to shift solenoid operation. The solenoid actuates hydraulic circuits controlling clutches or bands for gear changes.
Saab 750 C1396 Repair Cost
Replacing the lambda (O2) sensor wiring loom section on the Saab 750 costs $90–$160 at a body shop or auto-electrician. This is far cheaper than replacing the sensor itself when the sensor is otherwise functional — always inspect wiring before condemning sensors.
C1396 Description
C1396 engine trouble code is related to Ignition Coil A Primary/Secondary Circuit Malfunction.
Main Cause
The primary reason for C1396 OBD-II Engine Trouble Code is: Throttle/Pedal Position Sensor/Switch A Circuit Intermittent.
Common C1396 Misdiagnosis on the Saab 750
Fuel injector replacement is over-prescribed on the Saab 750 for C1396 when the actual fault is a weak fuel pump. Low fuel rail pressure causes lean misfire that looks identical to injector failure in static scan data without a live fuel pressure test.
DIY Repair Guide: C1396 on Saab 750
For Saab 750 owners without a scan tool, a free diagnostic check is available at most franchised Saab dealers during a courtesy health-check appointment. This provides the DTC number needed to research the exact cause of C1396 before committing to any repair.
Preventing C1396 on the Saab 750
Ensure the Saab 750 oil cap and dipstick tube seal are airtight. Even a small crank-case vacuum leak can cause the PCM to log C1396 and, over time, allows moisture-laden air to degrade the engine oil faster than the scheduled service interval.
Frequently Asked Questions — Saab 750 C1396
A: Temporarily clearing C1396 can help determine whether it is intermittent or persistent, but it does not fix the underlying fault. The code will return if the problem is still present. Do not clear codes just before an emissions test without a proper drive cycle.
