Did the vehicle pass the smog check?

No. Visual Inspection and Functional Check both passed, but the Emissions Test failed on both ASM test rows (15 MPH and 25 MPH).

Which emission readings caused the failure?

The HC (hydrocarbon) readings: 143 PPM measured vs. an 85 PPM maximum at the 15 MPH test, and 128 PPM vs. a 67 PPM maximum at the 25 MPH test. CO and NO measurements were within their listed maximums.

Did any visual/functional emission control components fail?

No. All listed items — including catalytic converter, oxygen sensor, fuel injection, spark controls, fuel evaporative controls, fuel cap tests, ignition timing (10 BTDC), OBD system check, and wiring to sensors — show Pass.

Is financial help available after failing a smog check?

Yes, the report states financial assistance may be available; applications are at the Bureau of Automotive Repair's website www.smogcheck.ca.gov or toll-free 800.952.5210.

What station and technician performed the test?

Technician Madrid, Cesar/EO147001; station number TC227311; software version/EIS number 1201/SX100210; no repair tech listed (N/A).

This document is a California smog check (Smog Check) vehicle inspection report showing an overall result of Visual Inspection: Pass, Functional Check: Pass, and Emissions Test: Fail. The Emission Control Systems Visual Inspection/Functional Check Results section lists individual components — fuel evaporative controls, spark controls, oxygen sensor, catalytic converter, fuel injection, wiring to sensors, air injection, vacuum lines/sensors/switches, fuel cap (visual and integrity), ignition timing (10 BTDC), liquid fuel leak, fuel EVAP test, other emission components, and OBD system check — all of which passed. The ASM Emission Test Results table shows the vehicle failed on both the 15 MPH and 25 MPH tests: HC measured 143 PPM (max 85) and 128 PPM (max 67), and NO measured 488 PPM (max 807 — within limit) and 419 PPM (max 746 — within limit); CO measured 0.01% against 0.54/0.45% limits, so hydrocarbons (HC) were the failing readings, highlighted on the document. The report includes information about financial assistance for failed smog checks via the Bureau of Automotive Repair (www.smogcheck.ca.gov, 800.952.5210) in English and Spanish, plus station information: technician Madrid, Cesar/EO147001, software/EIS 1201/SX100210, station number TC227311.
