2000 Chevy Metro LSI 1.3L 4-door P0705 Code: Transmission Range Sensor (TRS) Issue After Replacement

Model: 2000 Chevy Metro LSI Fault Code: P0705 Posted: 2017-08-02 18:52

I own a 2000 Chevrolet Metro LSI with a 1.3L engine, 4-door model, and recently encountered Diagnostic Trouble Code P0705. I replaced the Neutral Safety Switch (also known as the Transmission Range Sensor or TRS), but the code P0705 persists. P0705 - GM Powertrain Code: Transaxle Range Switch Circuit (M60 3-Speed Transaxle) Cause: - The Powertrain Control Module (PCM) did not receive any input from the Neutral Safety Switch during engine operation, or it received conflicting signals in Drive or 3rd gear for at least 5 seconds. This is a generic powertrain code applicable to all GM vehicles manufactured from 1996 onward. While the code indicates an issue with the transmission range switch circuit, troubleshooting steps vary by model and year. The TRS (Transmission Range Sensor) is responsible for signaling the PCM or TCM about gear position — Park (P), Reverse (R), Neutral (N), and Drive (D). A persistent P0705 suggests a wiring, connection, or sensor circuit issue rather than a faulty switch alone. I have already replaced the TRS, but the code remains. What should I check next? Any recommended diagnostic steps for this specific 2000 Chevy Metro LSI?

Why did you replace the TRS? Was it based on the P0705 code or another symptom?

The P0705 code specifically points to a circuit issue in the transmission range switch. The Powertrain Control Module (PCM) either fails to receive input from the TRS or receives inconsistent signals during gear shifts — particularly in Drive or 3rd gear for more than five seconds. This is a generic GM powertrain code, meaning it applies across multiple vehicle models and years, but the exact diagnostic procedure depends on the specific model year and transmission type.

The P0705 code indicates a circuit fault. After replacing the TRS, you should systematically inspect the wiring harness, connectors, voltage levels, and continuity (ohm readings) to ensure proper signal flow from the sensor to the PCM or TCM.

Without knowing which wires are positive or negative, it's difficult to perform a thorough check. Do you have access to an official wiring diagram for your 2000 Chevy Metro LSI? Where can I find one reliably?

AllData.com provides comprehensive diagnostic trouble tree and wiring diagrams for this vehicle. Alternatively, try revbase.com/BBBMotor/Wd — it may have the required schematics.

AllData.com charges $29.00 — I'm hesitant to pay until I confirm its relevance. The revbase.com link returned a server error: 'A potentially dangerous Request.Path value was detected from the client.'

Found this resource: http://www.revbase.com/BBBMotor/Wd/DownloadPdf?id=18897. This PDF includes two diagrams — one of which shows the TRS location and wiring.

Thank you for pointing that out, but I still need a legend or reference guide to interpret all item numbers (e.g., wire colors, connector terminals, PCM connector pins, cavity IDs) in the diagram. Without this, it's hard to use.

The information is available — including wire color codes, electrical connector terminal labels, PCM connector pinouts, and cavity numbers. These are essential for accurate wiring checks and troubleshooting.
