Obdii

Can anyone recommend a good OBDII scanner for an 04 rx8? I am trying to diagnose a P2096 CEL and I am working through the flow chart in the service manual. One step is to access the "O2S12 PID". Will all scanners be able to access proprietary PIDs? Thanks!

As an alternative, have you tried researching a bit:

Fairly common issue.

You could try the app torque and buy a cheap OBDII blutooth reciever from amazon for 25 or so. Don't know if that will get what you need though. It can scan the codes, but not sure about pids.

Its all a matter of how creative you are... It can certainly be done.

I programmed (their instrucvtions pretty easy) Horsepower, Miles to Go, Auto trans temp ( got it from Miata site), cat converter temp.

You can get fuel trim and air fuel ratios, etc.

I paidf $80. once for a dealwer to read one code; Never again.

You can llok up any code by googling it, and peiople will tell you how to fix.

Thye net is your oyster.

Here's what I've got for mode 1:

I've got Wideband around here somewhere... can't find it ATM moment though.

And here are the Mode 22 ones I've found:

Code:

obd.getHs().getEBT().sendATCommand2("ATSH000751");
					
final String tpmsPresBuf = obd.getHs().getEBT().sendOBDCommand("22C9011");
final String tpmsTempBuf = obd.getHs().getEBT().sendOBDCommand("22C9021");

final String[] tpmsPres = tpmsPresBuf.split(" ");
							
final float tpmsPres4 = Integer.parseInt(tpmsPres[tpmsPres.length - 2], 16) * 1.373f * KPI_TO_PSI_MULTIPLIER;
final float tpmsPres3 = Integer.parseInt(tpmsPres[tpmsPres.length - 3], 16) * 1.373f * KPI_TO_PSI_MULTIPLIER;
final float tpmsPres2 = Integer.parseInt(tpmsPres[tpmsPres.length - 4], 16) * 1.373f * KPI_TO_PSI_MULTIPLIER;
final float tpmsPres1 = Integer.parseInt(tpmsPres[tpmsPres.length - 5], 16) * 1.373f * KPI_TO_PSI_MULTIPLIER;

final String[] tpmsTemp = tpmsTempBuf.split(" ");
							
final float tpmsTemp4 = (float) (1.8 * (Integer.parseInt(tpmsTemp[tpmsTemp.length - 2], 16) - 55) + 32);
final float tpmsTemp3 = (float) (1.8 * (Integer.parseInt(tpmsTemp[tpmsTemp.length - 3], 16) - 55) + 32);
final float tpmsTemp2 = (float) (1.8 * (Integer.parseInt(tpmsTemp[tpmsTemp.length - 4], 16) - 55) + 32);
final float tpmsTemp1 = (float) (1.8 * (Integer.parseInt(tpmsTemp[tpmsTemp.length - 5], 16) - 55) + 32);

And for the record, my cheapo chinese BT adapter accesses those mode 22 PIDs just fine
