[QUOTE="Vinnie_B, post: 16803683, member: 201678"] P0153 - HO2S Sensor Circuit Slow Response (HO2S-21) **The HEGO Monitor checks the HO2S Sensor frequency and amplitude. If during testing the frequency and amplitude were to fall below a calibrated limit, the test will fail. You mentioned you have no cats. Did your tuner turn these sensors off? Things I would advise you to check that would generate this fault as well would be: [LIST] [*]Exhaust leaks [*]Shorted /open wiring [*]Improper fueling [*]***MAF sensor or wiring [*]Inlet air leaks [/LIST] ** If the o2 sensor is still enabled and being used in your current tune PO153 could be generated by these conditions. [LIST] [*]Contaminated HO2S sensor [*]Deteriorating HO2S sensor [/LIST] If you need Diagnostic Troubleshooting and help repairing electrical system feel free to reach out to me.
