Mitsubishi Space Star Ii P1260 Engine Trouble Code
What is Mitsubishi Space Star Ii P1260?
With Mitsubishi Space Star Ii P1260, 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.
P1260 on the Mitsubishi Space Star Ii
Owners of the Mitsubishi Space Star Ii should be aware that P1260 can appear alongside oil consumption warnings. Low oil pressure caused by a worn PCV system lets crankcase vapour contaminate the mass air flow sensor, sending erroneous readings to the ECU.

How to Fix Mitsubishi Space Star Ii P1260
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:
Gasoline engines use spark plugs to ignite fuel-air mixture. Proper timing ensures the explosion occurs when the piston is positioned correctly. Incorrect plug wire sequencing causes mistimed ignition, resulting in poor performance.
Technical Notes:
P1260 DTC specifically relates to camshaft timing. When cam timing is over-retarded, the check-engine light illuminates and this code sets. Verify VCT solenoid operation and check for contamination.
Mitsubishi Space Star Ii P1260 Repair Cost
On the Mitsubishi Space Star Ii, secondary air injection pump replacement for a P1260 code runs $350–$600. Because the pump is only active during cold starts, symptoms are easily missed. Requesting a cold-start emissions test at the workshop will confirm whether the pump is operating.
P1260 Description
P1260 OBD-II Trouble Code: Theft Detected Vehicle Immobilized is one of the definitions for the P1260; however your vehicles manufacturer may have a different definition for the P1260 code. Please check below for your specific
Main Cause
The primary reason for P1260 OBD-II Engine Trouble Code is: Manifold Absolute Pressure/Barometric Pressure Circuit High Input.
Common P1260 Misdiagnosis on the Mitsubishi Space Star Ii
Workshop technicians sometimes replace the entire ignition coil assembly on the Mitsubishi Space Star Ii when P1260 accompanies a cylinder-specific misfire. In many cases, only the spark plug in the misfiring cylinder has fouled; a $8 plug replaces a $140 coil pack.
DIY Repair Guide: P1260 on Mitsubishi Space Star Ii
Battery terminal cleaning on the Mitsubishi Space Star Ii is a 5-minute job that resolves a surprising number of P1260 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 P1260 on the Mitsubishi Space Star Ii
Keeping the Mitsubishi Space Star Ii battery in good health — testing specific gravity annually and replacing at first sign of degradation — protects the ECU voltage supply. Voltage drops during cranking cause sensor reading spikes that can spuriously store P1260.
Frequently Asked Questions — Mitsubishi Space Star Ii P1260
A: It depends on the severity. If the check-engine light is steady, it is generally safe to drive to a workshop within the next few days. If the light is flashing, pull over safely as soon as possible — a flashing light indicates an active misfire that can cause expensive catalytic converter damage within minutes.
