Year and Trim: 2004 Bonneville GXP
Helping a friend fix up their 04 GXP he inherited. Problems are as follows and action taken listed if any.

Has coolant low on DIC after adding coolant. He is double checking levels soon and I will update you when he updates me.

Has low tire pressure message on DIC even after checking / filling tires.

Intermittently receives notice to service stability system. Haven't looked into this.

P0108 - MAP high input. Replaced MAP sensor, code went away

P0336 - Crankshaft position sensor A (intermittent according to OBDII scan)

P0386 - Crankshaft position sensor B (current according to OBDII scan) - Where are the sensors located?

P1372 - Crankshaft poisition sensor circuits performance (Intermittent according to OBDII scan) - Does this have something to do with the other two being off?

P0496 - EVAP high purge flow ( Current according to OBDII scan) - replaced evap solenoid and code cleared

Any and all advice is appreciated!

Deja Vu, just answered this for someone;

P0108 - Means that the MAP sensor is probably faulty seeing something more than the maximum 5 volts.

P0336 - The "A" circuit of the sensor isn't functioning properly. The drivers of this could be a misfire (which you seem to have with a P0300 (there should also be a P030x which the "x" is the cylinder(s) affected), a bad CKP sensor, relector wheel damaged (teeth broken or just worn), metal shavings have built up on the reluctor wheel or the magnet on the CKP sensor, bad harness or shorted out wires in the harness.

P0386 - means that the CKP sensor has seen a signal voltage in excess of the normal 5 volts. The drivers of this could be a misfire (which you seem to have with a P0300 (there should also be a P030x which the "x" is the cylinder(s) affected), a bad CKP sensor, relector wheel damaged (teeth broken or just worn), metal shavings have built up on the reluctor wheel or the magnet on the CKP sensor, bad harness or shorted out wires in the harness.

P1372 is probably a result of the other two

The sensors (there are two), are located on the on the front side of the block just above the oil filter.

The rest is a search of the forum away;

Service Stability System =
Quote:
There are three pieces used in the stability system that require replacement when the stability system becomes inoperative and you've troubleshot it correctly. I have listed those above. In addition, the electronic brake control module (EBCM) can be a culprit too.

1) First you perform an ABS system check. If there is a fault in the ABS system, this is where the WSS comes into play. But NOT anything to do with the VSES!

2) you check that the VSES (Vehicle Stability Enhancement System) centers for roughly 30 seconds. If it doesn't, go to step 3, otherwise check all connections and wiring harnesses for intermittent connections.

3) Using your T2 (or equivalent), perform a steering wheel position sensor test. If the SWPS checks out, move on to the next step. If it doesn't, replace the SWPS.

4) Using your T2 (or equivalent), check the lateral accelerometer input voltage in the VSES. It should return about 2.5v. If it does, then the next step will be to test the yaw rate sensor. Otherwise, if it doesn't, replace the lateral accelerometer.

5) Using your T2 (or equivalent), check the yaw rate sensor. It too should return 2.5v. If it does, move on to the EBCM. If your yaw rate sensor doesn't return 2.5v, replace the yaw rate sensor.

6) Replace the EBCM. If it isn't programmed/setup properly, that could be the problem, and you'll be generating a C1248 or C1255M3 code and possible incorrect operation of the system.


Low tire pressure is probably resultant of the WSS noted above in step 1 above.

Coolant level issue is also a known item. The sensor, which is in the bottom of the overflow tank, "gunks" up. Many discussions of it in this section.
