13920 km - Two CEL codes P24B5 and P24C9

[Thorvald]

Well this isn't off to a great start... I had the radio touch screen "freeze" the other week (full shutdown of truck fixed that for now) and Saturday got the Check Engine Light. Thankfully had a Kiwi ODBII reader with me so I was able to pull the codes and clear them to see if they come back.

The codes were P24B5 and P24C9.

According to DTCDecode:

P24B5
Particulate Matter Sensor Heater Control Circuit Low
Causes:
FUSED IGNITION SWITCH OUTPUT CIRCUIT (SCR RELAY 2 CIRCUIT) OPEN/HIGH RESISTANCE
FUSED IGNITION SWITCH OUTPUT CIRCUIT (SCR RELAY 2 CIRCUIT) SHORTED TO GROUND
FUSED IGNITION SWITCH OUTPUT CIRCUIT (SCR RELAY 2 CIRCUIT) SHORTED TO SENSOR GROUND CIRCUIT
PARTICULATE MATTER (PM) SENSOR

P24C9
Particulate Matter Sensor Temperature Circuit High
Causes:
FUSED IGNITION SWITCH OUTPUT CIRCUIT (SCR RELAY 2 CIRCUIT) SHORTED TO VOLTAGE
GROUND CIRCUIT SHORTED TO VOLTAGE
GROUND CIRCUIT OPEN/HIGH RESISTANCE
PARTICULATE MATTER (PM) SENSOR

So hopefully just a "fluke" but will keep an eye on this.

Oh well , so much for that. Codes came back today, time to book a service appt. Grrrrr.

And... sure enough. It's the sensor and no parts to be had anywhere! 14,000km bought in December and now VOR'd.

Worst part is we are now down a vehicle in the family and had a camping trip next weekend....

If anyone finds these sensors I think I'll start carrying a spare!

Well will wonders never cease... the sensor was replaced a while back and I'm now at 40,000 km and boom... check engine light.

Scanned and P24D1 came up with pending P24B5 and P24C9.... same sensor gone bad again....
