Where is the Intermediate Shaft Speed Sensor Located in a 2004 Toyota Camry with P0793? | OBD2 Code Explanation

The intermediate shaft speed sensor is typically located near the transmission oil hose, close to the transmission input shaft. To access it, remove the battery and intake air box. The connector is usually upright and accessible from that area. A healthy sensor should read approximately 600 ohms when tested with an ohmmeter. If readings are outside this range or inconsistent, the issue may stem from a faulty sensor or wiring circuit — in which case, the ECM (Engine Control Module) may need to be reprogrammed or diagnosed further.

Thanks for the help! I was able to locate the sensor. After performing an ATF fluid change and replacing the transmission filter, I cleaned the sensor as my transmission fluid appeared dirty. However, the P079-than code persists. How can I accurately test the sensor's resistance using a multimeter? Is there a specific procedure for this?

To test the sensor with an ohmmeter, disconnect the sensor connector and measure resistance directly across the sensor terminals. A reading of approximately 600 ohms is normal. If the value is significantly higher or lower, it indicates a defective sensor.

Thanks everyone — I finally resolved the check engine light issue! The problem was a damaged wire in the connector leading to the intermediate shaft speed sensor. After inspecting, I found that rodents had chewed through part of the red wiring. I reconnected it and sealed the exposed section with electrical tape and heat-shrink tubing. The check engine light turned off after this fix.

Hi there — my sister's 2004 Acura Verso isn't shifting smoothly. It only shifts from 1st to 2nd and 2nd to 3rd, failing to reach 4th gear. After running an OBD2 scan, I found P0793. I cleared the code, and it shifted into 4th once — but then reverted back to 3rd. After replacing the intermediate shaft speed sensor and clearing the code again, it only reached 4th gear briefly before failing to shift beyond that. What could be causing this? Is a new sensor sufficient or are there other underlying issues?

Common causes of P0793 in vehicles like the 2004 Toyota Camry include: - A defective or damaged intermediate shaft speed sensor - Electrical faults in wiring between the sensor and ECM/TCM modules - Internal issues within the ECM or TCM - Defective related components such as input/output shaft sensors or shift solenoids - Low or dirty automatic transmission fluid (ATF) It's recommended to first check ATF level and condition, perform a thorough inspection of wiring harnesses, and verify sensor resistance with an ohmmeter. If the issue persists after these steps, professional diagnosis using a scan tool may be required.

My 2004 Toyota Camry XLE engine unexpectedly shuts off when driving through slow traffic. OBD2 scanning reveals P0793. I've already cleaned the intake air box twice using carbon-removing aerosol sprays with no improvement. A second mechanic suggested replacing a fuel-related component located under the rear seat near the fuel tank, claiming it might be faulty. However, he says the part appears fine and only needs cleaning — but after that, the issue remains. I'm now concerned this may not be related to the sensor at all. Could P0793 be linked to a different system? Any insights would be helpful.
