40) DTC P1309
This fault indicates misfire detection monitor malfunction. Turn ignition and all accessories off. Disconnect PCM 104-pin connector. Inspect connector for loose, damaged or corroded terminals. Repair as necessary. Install Breakout Box (014-00959), leaving PCM disconnected. Connect DVOM between test pin No. 85 and test pin No. 51 or 103 at breakout box. Using starter, bump engine in short
bursts for at least 10 revolutions. DO NOT allow engine to start. If voltage switches from less than 2 volts to more than 8 volts, check CMP sensor for correct installation. If sensor is correctly installed, replace PCM. If voltage does not switch from less than 2 volts to more than 8 volts, replace CMP sensor. Perform MISFIRE MONITOR REPAIR VERIFICATION DRIVE CYCLE.
Misfire Monitor Repair Verification Drive Cycle
1. On models with Fuel Level Input (FLI) circuit to PCM terminal No. 12, check fuel gauge and FLI PID value. Misfire monitor can only be tested if fuel gauge reads more than 1/4 full or FLI PID value is more than 15 percent.
2. On all models, start engine. Drive vehicle to a location where vehicle speeds can reach 55-60 MPH and then coast down to 40 MPH without traffic interference. Accelerate at wide open throttle to allow vehicle to shift at red line (if equipped with a tachometer).
3. Immediately return to normal speed limits. Accelerate vehicle speed to 60 MPH for 30 seconds. Take foot off accelerator and coast down to 40 MPH. Stop vehicle and repeat QUICK TEST.
