How to remove and install the Crankshaft Position Sensor on an Acura TL?

The CKP sensor is located at the liming bell crankshaft sprocket. For 2003 and earlier models, begin by raising the front of the vehicle and securing it on jackstands, then remove the engine cover. Disconnect the CKP sensor electrical connector, which is situated behind the right end of the engine, above the liming bell tensioner. Next, remove the timing belt covers, followed by the CKP sensor mounting bolt to detach the sensor from the engine. Installation is the reverse of removal. For 2004 and later models, raise the front of the vehicle and secure it on jackstands, then remove the engine cover. Proceed to remove the crankshaft pulley and the upper and lower timing belt covers. Remove the two nuts securing the shield for the CKP sensor wiring harness, then take off the shield and the CKP sensor. Detach the CKP sensor from the engine block by removing the sensor mounting bolt, pulling off the sensor, and disconnecting the electrical connector. Installation is the reverse of removal.

Acura TL Crankshaft Position Sensor

The Acura TL Crankshaft Position Sensor is the engine's timekeeper, performing constant readings on crankshaft angle and speed to enable the powertrain control module to fire spark and inject fuel at the correct instant. Mounted next to the crank pulley or the flywheel, it sends out electronic pulses that are paired with the cam data by the ECU to control variable valve timing, smooth idle and quick starts. Early TL versions utilized a robust inductive Crankshaft Position Sensor, which is a device that generates its own voltage as a toothed wheel passes the pickup, but its low-speed accuracy is limited. Later Acura entries in the TL lineup switched to a Hall Effect Crankshaft Position Sensor with an internal magnet and circuitry, which produces a nice clean digital signal during cranking as well as high revs, and this Crankshaft Position Sensor progression improved overall precision. Optical and magnetoresistive styles are a rare occurrence, mentioned only in testing. If there is a problem with the Crankshaft Position Sensor, the ECU does not have a reference point, resulting in misfires, stalling problems or no-start episodes. For the owners of modern Acura, checking wiring and secure mounting regularly helps keep an Acura TL running confidently.
